I am quite inexperienced with electronics. But I like to play a bit.
So, I will ask for some input.
I wish to build an electronic speed controller for an rc truck.
My truck spends a lot of time at low speeds.
It is geared very low.
The motor whine at low speed is very annoying, and is my reason for
attempting this.
My requirements are:
16khz switching speed
(to remove some of the motor whine at low rpms)
As few components as possible.
I am wanting to use a relay for reverse. So there is only
one drive side. (hope that makes sense)
I am using an 8M chip, and I can write the code, but I need help
with the components.
Any suggestions on the transistors that I need.
I would like to drive it/them directly from my chip.
I'm using a
4.5v battery for the receiver and servos
and a separate 7.4v battery for the motor.
