Hi everyone, i need to turn on something if a signal is HIGH for a certain period of time, and turn it off afterwards, basically, if the input is HIGH for 10 seconds it triggers and the transistor or relay in the output closes, after the signal goes LOW it shuts down, I've been trying with caps and resistors charge delay but it gets tricky with the discharge, im not sure that is the correct way, any ideas? Thanks
