A compiler is software that translates human-readable programming code into binary digits. When no EV3 Brick is connected, most of happens behind the scenes. This feature is really useful when you need to set thresholds in your programs for Wait blocks or when you need to measure how much a Connected motor shaft should rotate.

When you connect a sensor or a motor to an input or an output port on the EV3 Brick, the EV3 Brick recognizes the type of device automatically, thanks b to the Auto-ID feature. You can change the mode of the sen- sors for example, the Color, Reflected Light Intensity, and Ambient Light modes for the Color Sensor by clicking the related icons.

You can also reset the Motor Rotation sensor values by clicking the port names. Brick name Battery level the tools menu The Tools menu is located in the menu bar [see Figure 1 ]. Collapse bar setup browser N Image Editor: This allows you to create, import, or edit an image and save it to your project. Grouping blocks into a single My Block is useful for creating a small sequence that can be used as a module in many parts of a project or to make your programs look tidier.

They rotate motors, display text and images on the of your EV3 Brick. You The Flow Control blocks Figure control the flow of the can access the same tool from the Brick Information tab of program. Every program sequence begins with a Start block. As in the Brick Program App, here you find a for example, to program your robot to work with a new Wait block and a Loop block.

There is also a Switch block that sensor. You can access the same tool from block even if some blocks inside the loop are still running; the the Brick Information tab of the Hardware Page.

You can N Download as App: Using this tool, you can download a set the Loop Interrupt block to interrupt a specific Loop by program as an app, making it appear in the Brick Apps name, as every Loop block has a name label on top.

You may recall from Chapter 3 that the basic structures that make every computer program work are sequences of actions, choices, and loops. Each palette has a different color, and all the programming blocks belonging to the same palette have headers of the same color. For example, all Start Wait Loop Switch Loop the Action blocks have green headers, and all the Interrupt Flow blocks—like loops and switches—have orange headers.

Figure The Flow Control blocks palette The programming blocks will be described as soon as you use them in the following chapters. To find information about a particular block, look it up by name in the index. We will variables and arrays, manipulate data with Math and Logic learn about these blocks when programming the robots in Operations blocks, compare values, combine strings of text, and Chapters 10, 12, 14, and Each of these will be explained in You can download additional Sensor blocks from the the following chapters.

Project Content: Here is a list of all assets included in the project, grouped in categories—Programs, Images, An EV3 project file is actually an archive that contains all the Sounds, My Blocks, and Variables. Project Properties features the following: 1. Project Description: Here you can document your project by giving it a name and adding a main picture, a video, and EV3 brick to 2.

Alter- natively, close and reopen the EV3 Software. Right after the Start block, you have a Loop block, which includes all the other programming blocks. This is the Mode Selector, set to Count mode. The blocks. Brick Program in Chapter 3. Inside the Loop block are Move Steering blocks and Wait blocks. Here the Move Steering blocks are in On mode: The blocks turn on the motors attached to the specified Motor Ports, and then the program continues.

The time is expressed in place the mouse over the blocks or buttons, corresponding seconds, but you can specify values as fractions of a second, hints will pop up to guide you. For details, see EV3 Help like 0. Select the Chapter 3. When blocks are not connected to the Start block, they appear faded out.

In this mode, the Seconds and Brake at End inputs are also shown. Alternatively, drag them the Wait blocks right after it, and then delete the Wait block. The remaining blocks should move stop when the motion is complete.

In this mode, the Move together to fill the space left by the deleted block. Steering blocks pause the program flow until the duration has elapsed. You can see the complete program in Figure You can also enter a new value from reset the port.

Click the Block Exit Plug again to gram in the corresponding direction so you can view it in collapse the wire and move the blocks close together again. Click the end plug of a Sequence Wire to disconnect the blocks. These two blocks program flow have slightly different properties: The Move Tank block allows you to configure the power of the two driving motors sepa- rately, but for the Move Steering block, you must set the power and the amount of steering for both motors together.

To allow an EV3 program 50, like 45 or Keep experimenting to see how the to choose between two different actions, we use a Switch block.

How Build the program shown in Figure as follows: would you make it travel faster? Place a Loop block from the Flow Control blocks palette and leave it set to its default mode, Unlimited repeat forever. Place a Switch block inside the loop. Drag a Move Steering block into the True case of the Switch block at the top, indicated by a check mark. Add another Move Steering block inside the False case of the Switch block at the bottom, indicated by an x. In the imported line- Software features, tools, and work areas.

You learned how following program, notice how the Wait blocks are the programming blocks are organized in the Programming configured to wait for certain Color Sensor readings Palettes and, by importing Brick Programs, you took your first in Compare Reflected Light Intensity mode. Try to steps toward proper EV3 programming. You also learned how create a line-following program using a Loop block and to use Action and Flow Control blocks. The Switch block is shown in Flat view by default, which means that every case is visible.

If only one case contains programming blocks, you can keep it in Tabbed view, showing only the case filled with blocks. Otherwise, Flat view should be fine. To fit all the blocks inside them, resize the Loop blocks and the Switch blocks by dragging their Resize Handles, as shown in Figure In the Switch block, each case can be resized independently.

The Resize Handles are shown when the block or case is selected. In addition to measuring the proximity of objects, the IR Sensor can detect infrared signals from the Remote IR Beacon, allowing you to send commands to your robot just as you send commands to a television with a remote control.

The IR Sensor can also estimate its distance and orientation with respect to the Remote IR Beacon; this cool feature will allow you do fun things with your robots like play 6 tag, chase prey, or locate and reach a mission base. As you can see in Figure , it has four 7 12 small buttons labeled 1, 2, 3, and 4 , a large button 9 , and a 10 11 red Channel Selector switch A number engraved in red plastic in the Figure The Remote IR Beacon small circular window shows the current channel.

The large button 9 turns on Beacon Mode. When in 1 Button 1 Beacon Mode, the device transmits a continuous signal until any 2 Button 2 button is pressed or until one hour has elapsed. This feature allows a robot to follow a moving 5 Buttons 1 and 3 beacon or find its distance and heading relative to a fixed beacon. The plastic that houses these LEDs is a dark blue filter that 10 Buttons 1 and 2 lets only infrared light pass through it. You should be able to use the small buttons on the remote to drive ROV3R around.

There are two modes to choose from, as shown in Fig- Buttons pressed Motion ure To switch between modes, press the Enter button on the EV3 Brick. In the first mode, with the Remote Channel Selector 1 Turn right by pivoting on the right wheel. While in the same mode, you can 4 Turn right by going backward and pivoting on control motors connected to ports A and D with another remote the left wheel.

The second mode works similarly but receives commands from remotes set on channels 3 or 4. This same setup works for real-world vehicles, such as tanks or tracked vehicles like excavators. The human driver controls these vehicles by moving two levers, and each lever controls the motor that drives the track on the corresponding side. To switch between controlling channels 1 and 2 a and channels 3 and 4 b , press the Enter button on the EV3 Brick.

When you place the blocks and mouse cursor on an output, its shape should change into a wire spool. When you click an output, a wire plug appears. Place the plug on your desired input, and release the left mouse button. A robot uses the data provided by its sensors to perceive the world around itself. In Chapters 3, 4, and 5, we compared sen- sor readings against thresholds to trigger Wait blocks or Switch blocks. To directly access sensor readings, we can use the Sensor blocks found in the Programming Palette with the yellow tab.

Each Sensor block has several modes that serve different functions. In Measure mode, Sensor blocks provide measure- ments as numeric values to other blocks.

Some Sensor blocks like the Motor Rotation block and the Timer block also have a Reset mode, which resets their measured values to 0. A plug block and send it to the Move block for use as a Steering input.

The wire automatically follows the plug on the screen. This simple program makes ROV3R spin in place until you place your hand in front of the IR Sensor; then it will follow your hand, going straight until you remove your hand. Data Wires carry values from one block To delete a Data Wire, click and drag its end slightly to another.

To create the Data Wire, use your mouse to click away from the input the reverse of what we did in the last two steps shown in Figure To move a Data Wire, just click and drag it. To make the EV3 software rearrange and compact the wire in case things are getting messy , double-click the wire. Remember that the block that provides the output value must precede the block that receives the value in its input and that the blocks are executed in sequence from left to right: The output block where the wire begins must be to the left of the input block where it ends.

However, a Data Wire can skip over many blocks Figure This program makes the robot steer according to the distance and connect distant blocks. What happens? ROV3R should spin until you put your hand near the sensor. Once your hand is near, ROV3R should go toward your hand and follow it as you slowly pull it away.

How does this all work? When the IR Sensor measures a large distance when no object is near , its Proximity output sends a high value, around 80 to 90 percent.

When you place your hand in front of the sensor, its Proximity output drops closer to 0 percent. The Proximity value is carried by the Data Wire into the Steering input of the Move Steering block, which accepts values from — to percentage of steering.

The blocks currently being executed are highlighted with animated diagonal stripes. N O T E The origin of the terms bug and debugging is curious and controversial. Back then, real bugs moths and roaches sometimes EV3 software snuck into those huge relay-based computers, causing elec- trical and mechanical problems.

Engineers had to literally features for remove the bugs to get the computer to work correctly! But the EV3 Software allows you to do even more! Place the mouse pointer robot follows a hand. Using Figure as reference, add a Text over a Data Wire, and a small window pops up displaying the block Data Operations palette, red header and a Display block current value, as shown in Figure The number in the pop- to the program.

Note that this feature bines strings of text provided by its inputs a, b, and c. A string works only if you run the program from the EV3 Software is just a bit of text with any combination of letters, numbers, using the Controller Figure on page To if you run the program from the EV3 Brick menu, even if the enter characters into the Text block, you can either type text Brick is connected to the EV3 Software.

These If we had connected the IR Sensor output directly to animated stripes indicate the blocks currently being executed. However, when many numeric Wire pop-up display really help with debugging programs that values are displayed, what they mean is not always clear.

You is, finding and fixing errors, or bugs in programming jargon. This program is similar to the one in Figure Set the Display block to Text Grid to a single input. Then select Wired instead of static text by clicking the Text field in the header as shown in Figure The Display block should show a new Text input, where you will provide the variable text data to be displayed.

Set the Clear Screen input to understanding True as indicated by the check mark under the eraser icon so that the block will clear the screen every time it is executed. To help differentiate the data types, Numeric, Text, Logic, Numeric Array, and Logic Array inputs have different plug shapes, and the corresponding Data Wires have different colors.

These are shown in Figure A character set in Large font 2 is two rows and two columns wide. Download and run the program. Also, a logic value can be converted to a numeric value —but not the other way around. Computers like the EV3 Brick represent all kinds of data using only the binary digits 0 and 1, which are equivalent to the truth states False and True, respectively.

In fact, there could be several options. For example, should any nonzero number be converted to True? Or should any number less than a certain threshold be converted to False? For example, because the triangular point arithmetic operations, such as dividing 3 by 10, shape can fit into the round or square shape, we know that a the result of which is 0.

If you did the same opera- logic value can be converted into a number or text. Table lists all possible conversions. Array first and only element of the You can reuse this concept in many creative ways. For resulting logic array. Or you could put the beacon in the corner of a room and Array first and only element of the have the robot return to it, even after a long exploration, like resulting numeric array.

Switch block is in Tabbed View. To disable Beacon Mode, press any other button. To pass values through Switch blocks in Flat View, you need to use variables. First of all, the entire Move Steering block. For example, in the program shown in sequence is set to repeat forever by using a Loop block in Figure , the robot will steer toward the beacon with steering Unlimited mode. When the heading is Channel input set to 1. It has three outputs: near 0 frontal , the robot will drive straight toward the beacon.
