Electronics Circuit

The group looked into how to provide power to the circuit. They found out that the Arduino UNO controller they had been considering using draws 7-12v. The motors draw 2.7v and the uno only outputs 5v. To run all three motors each one will have to be run through an A4988 stepper motor driver carrier, available from pololu. This device can receive logic voltage commands from the arduino but also receives voltage from the power supply to power the motors. It uses between 8 and 35v. We need three of them, one for each motor. The motors then get their power from the batteries, using the motor driver as an intermediary. The motor driver receives a logic voltage from the micro controller that regulates how much voltage to run to the motors.
