Switching Control Signal

Hey guys,

So what I want to do is switch the control of a stepper motor from a computer to an arduino once a switch is hit. I have provided a circuit that should work … I am not the best at electronics so please tell me if it seems ok. The outputs of the Arduino and the Computer are going to be some sort of controls signals for a stepper motor.

Will this work?

Thanks in advance :slight_smile:
Picture is attached.

Your circuit is so so, its not the correct way to do it, but it may work. I can tell you, you will need a pull down resistor. 4.7K should be enough.

Look up the proper way to use transistors.

What is the correct way to do it, if I may ask? :slight_smile:

With just transistors, it will get a little confusing. However if you want a simple way to do it, go with a DPDT relay or two SPDT relays.
