I'm trying to build an RC car out of an old chassis with no electrics in it.
I looked at quite a few failed attempts of getting a 7.2V motor to run through Arduino and no one had any real solution and it was a lot of old locked threads. I think though the problem is they were trying to use the same power supply for both Arduino and motor, I don't have such an issue.
Is this as simple as using an Arduino on it's own power to control a transistor (with a resistor) with a motor and the separate load going through aforementioned transistor?
I do have a motor board on the way
I am also looking at a few other options and want the ability to reverse ... any hints, tips or readme's appreciated because I can only see how to go faster. I'm pretty much putting this together from various sources while hopefully doing their tutorials at the same time.
I also have RF and BT on the way and ultimately it's a big racing engine I want to drive but this is what I am ordering just now

Also is the reason RC cars use a resistor between each connection and the motor case instead of a diode from negative to positive (like I have seen in all the stuff I read) is to eat load in both ways?
I'm going to use two thumbsticks to control it over RF and with any luck make an app for over BT for mobile devices. Steering will be done with a servo. Accelerometer is on order as well as that line following module and hopefully this project will cover enough for me to get going.
I'm experimenting with an R3, but I also have other options, am I even using the right board for the job long term? I do have a few different kinds of ESP32 coming including from Makerfabs.
Thanks in advance.
