Sorry for not being very specific i decided to break the prject down into control then onto the motor and pulley, then adding a timer, may need to think of some kind of shut off in case the cables get caught up to prevent damage in the process was not actually telling members what my overall plans were.
Hope to use this circuit as a master control for a motor that will drive the coop door up and down currently based on light levels,
Looking into what spec motor i will need, the door is not very heavy so nothing more than 1 kg pull needed, maplins have a few that will work on 3v supply, so i need the circuit to trigger open in the AM and close in the PM, based on light levels, once i sort out the hack for analogue dc timer i will swap the circuit to be triggered by on off signal from the timer
