To set up and program the Crumble controller, please follow these steps:
1. Gather the necessary parts included in the class kit, such as the Crumble controller, micro-USB cable, corrugated plastic sheet, crocodile leads, motor, motor mount, bulb holder, bulb, and LED. You will also need a computer with an internet connection.
2. Assemble the components by screwing the bulb into the bulb holder and fitting the motor into the motor mount. Cut out a square base from the corrugated plastic sheet.
3. Attach a rectangle of corrugated plastic sheet to the Crumble controller using double-sided tape. Make sure to attach it to the side without components. This rectangle provides height for the crocodile clips to attach to the Crumble contacts.
4. Connect the micro-USB cable to the Crumble controller and plug the other end into a USB port on your computer.
5. Set up a destination folder on your computer called 'Crumble' and download the Crumble software from the provided link. Install the software by running the set-up wizard and choosing the destination folder you created earlier.
6. Once the software is installed, open it and construct a program to run the motor at 50% power for 5 seconds. Drag and drop the necessary commands from the list on the left-hand side of the screen. Attach the commands to each other to create the program.
7. Click on the green arrow to run your program. The motor LED on the Crumble controller should glow red for 5 seconds and then switch off. Save your program in the Crumble folder.
8. If you have the 2xAA battery holder, tie the battery snap wires in a reef knot to prevent accidental short-circuiting. Fit the cells into the battery holder and stick it to the base. If you have the 3xAA battery holder, tape a cut-out piece of corrugated plastic to the underside of the battery box and then stick it to the base.
9. Connect the circuit as shown in the instructions. Push the battery snap firmly onto the battery holder terminals or switch on the 3xAA battery holder. Run the program and check if the motor shaft turns for 5 seconds and then stops.
10. Disconnect the crocodile clips from the motor terminals and attach them to the lamp holder terminals instead. Run the program and check if the lamp comes on for 5 seconds and then goes off.
11. Disconnect the crocodile leads attached to the lamp and use them to connect the LED to the Crumble. Ensure that the longer leg of the LED is attached to output A and the shorter leg to the negative (-) terminal next to it.
12. Start a new program and set it up to turn on the LED for 3 seconds and then turn it off. Run the program and check if the LED behaves as expected. Save the program.
13. Disconnect the LED and its crocodile leads from the Crumble. Switch off the 3xAA battery holder or unclip the battery snap from the 2xAA battery holder to conserve battery power when not in use.
Your Crumble controller is now set up and ready to be used for various projects like the colored spinner, traffic lights, chair-o-plane, or nightlight. For further details and troubleshooting, refer to the provided resources and the Crumble lesson plan.
