Greetings,
Well I'm not exactly a "chicken farmer" but do have chickens and need some help with a circuit to activate the coop door latch. The latch will be a solenoid cabinet latch requiring 12VDC .6A supply. I have the power supply but now need to build a control circuit.
In the coop is a digital timer which is used to turn on a light every morning for about 2 hours. I would connect the power supply to that so the door will unlatch at the same time. As you can see, there would therefore be constant power to the circuit during those 2 hours. My search through these forums and elsewhere seems to indicate some type of 555 circuit would work to provide a 1-2 second pulse to activate the solenoid. I'm not sure however if any of those I've seen can provide one pulse only while input power remains "on".
Any assistance or guidance in the proper circuit design would be greatly appreciated , thanks.
