I used an h-bridge to reverse the current of a peltier plate, which was the same as this video
Beginning Peltier Cooler - H-Bridge - YouTube.
In the video, he had to physically remove a wire and place it somewhere else to reverse the current of a peltier plate. I was wondering how would I do it without removing a wire?
Also how do I control the current flow with an Arduino? In the image I provided, I figured out how to control the current with just the peltier itself without reversing current or anything
Would the circuit for the DC motor controlled by a L293NE h-bridge work if I just replace the DC motor with the peltier plate?
