Hey all,
Wanting to create an up/down counter that uses a photogate as a trigger, and a 12 segment LED bar graph to display the count. It will need to begin at full illumination, turning off one at a time on activation of the photogate. Will also need a reset switch, though I'm thinking a simple break in the circuit to turn off when disengaged, reverting to full illumination when power restored would do?
Wondering if I can retrofit a standalone up/down counter kit, or whether I'd need to go as far as to invsst in an arduino board and learn code? if there's a route that achieves what I need that avoids going to that extent, id prefer that.
Size and power both small if possible.
I've done some reading, but without a firm point of reference on which to draw a bearing, I fear I'm going in circles and not getting anywhere.
Any help much appreciated!
