I'd like to use an H-Bridge AND send PWM signal.
I've used this schematics: http://itp.nyu.edu/physcomp/Labs/DCMotorControl and use the PWM signal inside the enablePin. But the H_Bridge is getting very hot.
Am I wrong?
I'm using and H-Bridge but not for driving a motor, instead I'm driving a peltier cell (like this one: https://www.sparkfun.com/products/10080). What I'm trying to achieve is to have a fixed peltier cell and to have in the same side sometimes hot, sometimes cold. This behaviour is done by switching the positive and negative with the H-Bridge. To control how much cold and how much hot I'm using PWM.
