I was reading some forums about the 555 timer and i have a problem somewhat related to it. I have a device that is motion activated that powers and Solenoid for approximately one second, my goal is that when the motion switch is activated that i can adjust the amount of time current is flowing through the electromagnet(maybe have current flow through the solenoid between 1-5 seconds). I was curious if there is anyway possible to have the current flowing through the electromagnet adjustable by time? Thank you in advance.
