Hey guys. I am trying to create a circuit that is capable of interrupting a circuit for a adjustable amount of time. Basically I want to use a dial to change the time I am breaking the ground on a circuit in a car. I would like to use a momentary button to trigger the timer and open a circuit for anywhere between .01 and .1 seconds. I would appreciate if you guys could help me come up with a way to accomplish this. I understand I will have to have a momentary switch, a timer, a dial, and a relay to control the load. Thank you
