Hi All,
There seems to be a short coming of the 555 in its Monostable form thats holding me back. The function of the circuit in question is to protect a solenoid from burning out when a push button is held down to long. The venerable 555 seemed like the perfect solution. So what is happening is when the trigger is held low the solenoid on the output closes and never releases. What I want to happen is when the trigger is held low the the output goes low and releases after 2 seconds. Is there a simple solution Im just missing? Or is the 555 just not the chip for this circuit. I can built it with a attiny85 but that seems like a big waste of silicone.
Thanks Jeff
