Hey guys a little new to this forum, need some advice
So I found this circuit on a video(see image above) I was watching that alternates the polarities, I set it up on a bread board and It works perfectly with normal switches but I tried using a TIP120 and a RFZ44N transistor with the arduino. The problem is the transistors keep turning into resistors when the voltage is applied to the gate pin. Any advice on what transistors I need to use? or what im doing wrong?
