Building a small 3 motor RC bot. How do I make the receiver -> Ardu Micro -> Pololu Controllers communicate?
Bought 3 x tamiya gear/motor units, 2 for the wheels and one for the "weapon". Further research suggested that the
Tamiya RC260's motors need low voltage 3 - 4.5v max. Very few speed controllers go this low but the:
Pololu DRV8833 does, but will not interface with the:
Spektrum AR6100e directly, so we needed a:
Arduino Micro to link the RX with the motor controllers.
My questions revolve around 1) how to power the various units 2) how to make the Arduino hear the PWM signals and transmit to the controllers, etc., 3) I heard a heat sink would be good for the (Ardu?Controllers?), etc.
A rank adult robotics beginner here with electric RC Airplane experience, just looking for advice on where to look for info, or a tip on where to find where people have handled this before with low-V motors.
Thanks
