Hi
This is not my circuit but I needed it to work in the way I needed it for a project I am currently designing.
My challenges were to get the up and down counting to only be activated by one "button" although in reality this will be via a Photo Transistor and LED combination. This does work with what I have done but sometimes when switching from up to down via the two way switch it either adds 1 or subtracts 1.
Can anyone see the obvious that I may have missed please.
TIA
Derek
