Thank you HarryA

Hi i would like to build a circuit to protect my fridge from running to soon after being swirched of. So there would be a 240 V AC IN (from grid) and AC OUT (to fridge) and when the AC IN is switched off, there must be no AC OUT until about 10 minutes after it was switched off, even if the AC IN is switched on immidiately after being switched off.The fridge has draws start up power of about 900watt and running at about 140watt. Could you help with this? Thank you very much Redge

Good day all I have very basic electronic knowledge and can build basic circuits. I am building a tracking device that will turn my solar panel from east to west during 8 hours. The device will be powered by a 12v dc motor that will turn a threaded rod to move the panel through about 90 degrees. the motor will be controlled by a 12 relay. I need a circuit diagram that will power the relay to run the motor for 2 seconds at a time, but I would like to be able to adjust the time between runs from approx 30 sec to 5miniutes. also if possible, the motor must reverse after 8 hours until stopped by a limit switch. Any help would be appreciated Thank you Redge

I came up with this circuit, any comments?

Thank you

Thank you Harry, just to be sure, for input I will close a switch (it stays closed) between 'pulse in' and ground and that will give me a momentary 5V pulse at 'pulse 1 out'. When I open my switch again, it will give me a momentary 5V pulse at 'pulse 2 out' ? Do I understand it right? I appreciate your help

I need a circuit that gives momentarily contact when I close a switch and will give another momentarily contact when I open the same switch again.So when I switch a switch on there must be a circuit that acts as a push button switch and when I switch that switch off again it must act as another separate push button.I have a device that switches on with a push button and switches off with another push button. I want to switch the device on and of with a thermostat by using a circuit that connects the thermostat to those two push buttons, so that i can still use them to switch the device if I want to.
