Hey, I’m relatively new to electronics and was just after some advice on how to wire up this circuit.
All it has to do is have a 7 segment display that every time 1 mico switch is pushed the number advances by 1, and when another mico switch is pushed the number decreases by 1. Ideally this counting would be done without the display turned on. Only when one of the switches to increase/decrease the number is pressed would the display turn on for maybe 2secs to show the new number (plus possibly another button to turn the display on just to see the number, without changing it). Min number shown would be 1, max 7.
The best way I have seen of doing this so far is with a controller, the only downside being it needs 4xAA for the tutorial pack (although maybe a custom circuit would need less) as I really was imagining 1xAA of even a button cell.
Any help would be great.
Cheers
