I will be putting together the well known pwm controller box project. The goal is to have this controller be multifunctional in that I would like to be able to use it as a stir plate controller before brew day and use it as a heating element controller on brew day.
Could someone with experience building pwm controllers tell me if it is possible to have this much range in the controller to function in either mode with one design? Or will I need to figure out a way to set a toggle switch to use different caps in order to adjust the duty cycle.
