Hi everyone,
I am working on a project that requires me to turn on a solenoid for one second only. I was using a 555 timer in a monostable setup and had it working but it has since stopped. My understanding of a 555 timer is that if once you take the trigger to ground the output remains high until you return the trigger to high (via say a 10k resistor). What i want to do is take the trigger to ground, thus setting the output to high, and then 1 sec later returning the output to low, regardless of weather the trigger is still grounded.
I am trying to switch a transistor IRF640 on with one second of +5v to its gate which turns on a solenoid for one second.
Any advice would be great
Thanks!
