Hey Everyone - I've got openplotter up and running on an RPI4 and the motor control 'motor.ino' loaded onto an Arduino uno. Everything seems to be working ok,(with the exception of a possibly bad mpu9255)
What I'd like to be able to do is have the Arduino drive a couple of relays, or drive a couple of transistors I can switch the relays on/off with. The motor I have already has a suitable DC power supply that has a forward/reverse switch as well as speed control. I'd like to substitute the forward / reverse switch for a couple of relays driven from the autopilot. So far as I can see motor drive only available via pwm or h bridge, neither of which will work as my motor can pull over 20A easy.
Anyone got any ideas on how I can achieve this?
