RC transmitter controlled stepper motor, how to do it?

Dear all,

I couldn´t find advice elsewhere, so I am asking your help:

I need to control a stepper motor like Nema 17 with my RC transmitter (afhds 2A) and Uno. Have you seen some good instructions on that or maybe you self know how to do it?



Controlling a stepper motor and getting data from an RC receiver (presumably you do have a receiver?) are two different tasks and you should start with two separate programs for them. When you can get both of them to work separately it will be time to combine them.

Is your RC transmitter / receiver the common sort of thing that is used to control servos in, for example, a model airplane? If so, your Arduino program will have to measure the width of each pulse and convert that to a suitable number.

If you have the option I think it would be much easier to build a wireless control system using a pair of nRF24L01+ transceivers. Have a look at this Simple nRF24L01+ Tutorial

For controlling the stepper motors these links may help Stepper Motor Basics Simple Stepper Code



My RC tx&rx are very common type (afhds 2a).

Looks like I will take your advice and try that nRF24L01...

Have a nice week!
