I need to control an old projector that doesn't have an auto turn on on power. I thought of making a 555 timer circuit I saw on the internet.
It turns the LED (in this case it would be my relay) on after a certain time, and it stays on.
I need it to stay off for 10 seconds after power and then turn the LED/relay on, wait another 2 seconds and turn the LED/relay off and stay this way.
The relay will work as a button switcher connected to the power button of the projector.
Can anyone help me solve this? I have some knowledge of electronics, but not at this level I guess.
