Discuss design ideas.

Sketch out ideas and consider which input sensors and output modules will be used in the design. See page 3

Consider building components and cost.

3. Build A Prototype

Build a working prototype of the design including an example program/sketch. See pages 4 - 5

4. Test & Improve The Design

Test & improve the design for performance and consistency.

Identifying Inputs & OutputsList all of the input sensors and output modules used in the design. This information will be important as you develop a sketch/program that will be uploaded to the ROKduino and used to control the design.

InputsList all of the sensors that are used in the design and identify which input ports they are connected to.

OutputsList all of the output modules that are used in the design and identify which output ports they are connected to.

Developing a Program/SketchThe ROKduino can be programmed to read information from sensors connected to input ports, process that information into relevant commands, and send those commands to modules connected to the output ports. On the following page, start writing out what you want your build/project to do based on the input sensors and output modules that were used in the design. This will be helpful as you prepare to create an actual program/sketch on a computer. Once you have everything written out, you can go ahead and create a program/sketch on your computer.

Example: If the Bump Sensor that is connected to Input Port #1 is pressed, then the Motor Module that is connected to Output Port #1 should rotate Clockwise (at full speed) for 3 seconds and then stop.

* Sensor names listed on page 3.

* Output Module names listed on page 3.

ROKduino TroubleshootingThe following guide can be used to troubleshoot common issues that may arise when working with the ROKduino and Arduino/Ardublock software.

Software Installation Issues

1. Can’t locate Arduino software on the computer ?

Mac - In the applications folder, locate and select Arduino. If Arduino is missing from the applications folder, visit kidsparkeducation.org/downloads to download ROKduino software for MacOS.

PC - In the applications folder, locate and select Arduino. If Arduino is missing from the applications folder, visit kidsparkeducation.org/downloads to download ROKduino software for Windows.

2. Can’t locate Ardublock software on the computer ?

Mac - Visit kidsparkeducation.org/downloads and run the MacOS installer to download all ROKduino software including Ardublock.

PC - Visit kidsparkeducation.org/downloads and run the Windows installer to download all ROKduino software including Ardublock. Note: Each new user will need to run the User Installer that will be downloaded on each user’s desktop. Look for the Kid Spark icon located on the desktop.

Operating Issues

1. Can’t get sketch/program to upload to the ROKduino?

a. Make sure the ROKduino is plugged in to the computer via USB.

b. Make sure the correct USB port is selected.

- Go to Tools -> Port -> ROKduino Note: If the ROKduino option is not available, try unplugging the USB and reconnecting it to a USB port. Repeat this with a different USB port if neccessary.

c. Make sure the selected board is set to ROKduino.

- Go to Tools -> Board -> ROKduino

d. Reset the ROKduino.

- Press and hold the reset button on the top of the ROKduino while simultaneously uploading a program to the ROKduino. Release the reset button after the program has started uploading.

2. Program will upload to the ROKduino, but not powering Motor Modules or Light Modules?

a. Make sure the ROKduino is powered on.

b. Make sure the program that you created is correct.

- Double check each step of the program and change if needed. Note: pay special attention to inputandoutputvalues,andlookforpossibleconflictswithinthesketch.
