Hello All,
I'm trying to design a circuit that moves a servo to its limit after a certain delay. The project it is for has a price limit of $10 and a deadline coming up, so I designed a simple, tiny circuit using the 556 and have already sent the boards to fab. The schematic is attached.
What I need help with is determining the values needed to get the servo to move to its limit after x seconds. From what I've seen on the internet, the 555 can't provide much time between pulses because of its 50% minimum duty cycle, but it is never explained how servos handle this. I've seen an ideal period of 20ms, but what is the minimum 'off time?'
