An Arduino controls all of the electrical components on BB-8. The Arduino is connected to various other components, including motors and a bluetooth module, to drive BB-8.
Circuit Design
Here is the layout of our circuit:
The circuit includes an Arduino, a motor shield, and an HC-05 bluetooth chip. The bluetooth module pairs with a laptop and connects to the Arduino to send and receive commands. The motor shield sends power to the motors to drive them.
Parts Used
- Arduino Uno
- Adafruit Motor Shield v2
- HC-05 Bluetooth Chip (chip that recieves bluetooth sinal and sends it to the arduino over serial.)
- 3 x 18650 Batteries (Run in series for a total of 12V)
