Controlling a Brushless Motor via RS485

This repo contains the Arduino code and Fritzing sketch for controlling a Brushless motor via RS485 communication.

Use

Master's button:

• rotation - changes the direction of the rotation
• motion - spins the motor's shaft for 2 seconds

TODO

• use a toggle switch for the rotation button
• use global constants for e.g the delay
• use a function for showing activity on the led
• use half-duplex communication to avoid running the motor when "spamming" the motion button
• [circuit] perform real tests (with a long cable!)
• [circuit] consider the use of a ground wire in the RS485 link, in order to reduce noise¹ (not connecting together Master's and Remote's ground)
• perform tests with a real motor
