I need help with all of it, I know very little about electronics. Fortunatly I have a colleague at work who fixes everything and draws lots of circuit diagrams of everything. he said if I get the circuit diagram he could build it for me. I have 4 blinds running on electric motors that I have created pulleys for and fixings. I want to press a button and they will go up for X amount of seconds until it reaches the top. Unless as you say limit switches work better. I dont suppose you could point me in the right direction?
Regards,
James
