Hi, i need to know how to reverse the polarity on a motor. I'm planning on building a robot with a pushbutton switch in front a when it runs into something the switch is pressed and reverses the motor polarity. I'm hooking the switch up to a 555 timer and somehow plan to use the output to reverse polarity of the motor, but I don't know how. If anyone can help me, please do.
