1 Systems of Technology - Robotics: Section 3 The Arduino IDE & ArduBlock Instructions/Build Plans v2.0 Team Members: Introduction 1. Locate/Open: The Arduino IDE & Ardublock - Video Tutorial. 2. Assemble: Ellipse Mechanism (Build Plans/Cable Diagram on pages 7-11). The Arduino IDE 1. On a computer, Open: Arduino and become familiar with the different components of the program. New Creates a new sketch. Upload Compiles code and uploads to the ROKduino. Verify Checks the code for errors in compiling. Open Presents a menu of all the sketches in a sketchbook. Save Saves the sketch. Serial Monitor Displays data or information being sent from the ROKduino. Tab Opens or selects new tab. Text Editor Where sketches are written. Status Bar Displays if code was successfully or unsuccessfully uploaded to ROKduino. Text Console Displays complete error messages. The Arduino IDE is used to write text-based programs that are uploaded to the ROKduino. Programs that are written using the Arduino IDE are referred to as sketches. 1

2 ArduBlock 1. On the top menu bar, Select: Tools > ArduBlock. 2. Become Familiar: with the different components of ArduBlock. New Creates a new sketch. Save Saves the sketch. New Creates a new sketch. Containers Contain different blocks of code that can be used to create a sketch. Code Blocks Used to create sketches that can be uploaded to the ROKduino. Block Discard Area Used to discard unwanted blocks from the sketch pad. Block Discard Area Sketch Pad Where code blocks are used to create a sketch. Each code block used will be converted into a human-readable line of code in the Arduino IDE. Serial Monitor Displays data or information being sent from the ROKduino. Upload Compiles code and uploads to the ROKduino. ArduBlock is a visual programming tool that simplifies writing sketches by using blocks of code. After a sketch is created in ArduBlock, it is converted and organized into a human-readable, textbased sketch in the Arduino IDE, and uploaded to the ROKduino. 2

3 Setup Instructions 1. Connect: ROKduino to a computer using the USB cable. 2. Power ON: the ROKduino. 3. Click on: the Arduino window. 4. On the top menu bar, Select: Tools > Port > ROKduino. Creating a Sketch 1. Click on: the ArduBlock window. 2. In ArduBlock, observe: the Yellow Program Block. 3. Connect: a Motor Module Block to the loop section of the program block. 4. Observe: the values that can be adjusted on the Motor Module Block. 5. Click: Upload to Arduino. 6. Observe: the Ellipse Mechanism. The Ellipse Mechanism should be rotating clockwise at full speed. Since the Motor Module Block was connected to the loop function in ArduBlock, the ROKduino will continue to command the motor module to rotate clockwise, at full speed, over and over again. 7. Observe: how the information from the blocks in ArduBlock is converted into a human-readable, text-based sketch (program) in the Arduino IDE. ArduBlock Arduino IDE 3

4 Adjust Speed and Direction 1. Adjust: the speed of the Motor Module Block from 1023 (full speed) to Adjust: the direction of the Motor Module Block from clockwise to counter-clockwise. 3 Click: Upload to Arduino. 4. Observe: the Ellipse Mechanism. The Ellipse Mechanism should now be rotating counter-clockwise at a reduced speed (750). The speed and direction of the motor module can both be adjusted. Try adjusting the speed and direction of the motor module yourself! Incorporate the Light Module 1. In ArduBlock: connect a Light Module Block to the bottom of the Motor Module Block. 2. Observe: the values that can be adjusted on the Light Module Block. 3. Adjust the output # on the block to: 2 (The light module is connected to Output # 2 on the ROKduino). 4. Click: Upload to Arduino. 5. Observe: the Ellipse Mechanism. The Ellipse Mechanism should be rotating, and the red light on the light module should be illuminated at full brightness. The color and brightness of the light module can both be adjusted. Try adjusting the brightness and color yourself! Use a Delay 1. In ArduBlock: connect a delay block to the bottom of the Light Module Block. 2. Right Click: on the Motor Module Block and select clone. 3. Drag and Connect: the cloned set of blocks to the bottom of the delay block. 4. Adjust the values of the top Motor Module Block to: Output - 1, Speed , Direction - Clockwise. 5. Adjust: the values of the top Light Module Block to: Output - 2, Brightness , Color - Red. 4

5 6. Adjust the value of the top delay Millis block to: Adjust the values of the bottom Motor Module Block to: Output - 1, Speed , Direction - Counter-Clockwise. 8. Adjust: the values of the bottom Light Module Block to: Output - 2, Brightness , Color - Green. 9. Leave the value of the bottom delay Millis block at: Click: Upload to Arduino. 11. Observe: the Ellipse Mechanism. A delay is used to pause the execution of a program or sketch. In this example, there are two 3000 milllisecond (3 second) delays being used. The Ellipse Mechanism will execute the following set of commands for three seconds: A. Rotate Clockwise at full speed. B. Illuminate Light Module Red at full brightness. Then, the Ellipse Mechanism will execute the next set of commands for three seconds: A. Rotate Counter-Clockwise at full speed. B. Illuminate Light Module Green at full brightness. Since these sets of commands are connected to the loop function, this process will continue to be executed over and over again. 5

6 Lesson Challenges Complete the following challenges using the Ellipse Mechanism and ArduBlock. Place a check in each box as each challenge is completed. 1. Using ArduBlock, create a sketch that commands the Ellipse Mechanism to do the following: Loop Function A. Rotate the Ellipse Mechanism counter-clockwise, with a speed value of 850, and B. Illuminate the light module green, with a brightness value of Using ArduBlock, create a sketch that commands the Ellipse Mechanism to do the following: Loop Function A. Rotate the Ellipse Mechanism clockwise, with a speed value of 1023, and B. Illuminate the light module green, with a brightness value of 250 For 3 seconds (delay) Then A. Rotate the Ellipse Mechanism counter-clockwise, with a speed value of 800, and B. Illuminate the light module red, with a brightness value of 500 For 3 seconds (delay) Disassembly & Cleanup 1. Upload: A blank sketch to the ROKduino. 2. Power OFF: the ROKduino. 3. Close out: Arduino & ArduBlock. 4. Disassemble: Ellipse Mechanism. 5. Organize: Components back into Programmable Robotics Module. 6
