Circuit Documentation

Summary

This circuit integrates an Arduino UNO with an Arduino Motor Shield (Rev3) to control two bipolar stepper motors. The system is powered by a 2x 18650 battery pack. The Arduino UNO serves as the central processing unit, running embedded code to manage the operation of the motors via the Motor Shield, which directly interfaces with the stepper motors.

Additional Notes

• The code provided for the Arduino UNO is a template with empty setup and loop functions. The actual implementation should include initialization of the Motor Shield and control logic for the stepper motors.
• The documentation file associated with the Arduino UNO code is empty and can be used to provide additional details and usage instructions for the code.

This documentation provides an overview of the circuit's components, their connections, and the initial code structure for the Arduino UNO. Further development of the code is required to achieve the desired functionality of the circuit.
