Ok, i'll explain my secret weapon
I have 8 buttons that will control relays. One button corresponds to one relay. If itīis pressed i turn on the relay and stays on for 20s or 40s (depending the position of a switch). If one button is pressed while one relay is on the time goes to begin and the two relays stays on again 20s or 40s. On led is on if one relay is on...
Hereīs my secret weapon
It was simple if i was using PIC16F872 (thatīs the PIC i know better...)
My pulse itīs 200ms and the time itīs not critical (if i have 17s instead 20s thatīs ok)
