I have this component called a breadboard friend. It has a 9V battery that is lowered to 5v so we can power most AOI logic chips. It has a built in 555 timer and a potentiometer. It has 4 leds to link outputs from our logic circuits to - and it has 4 spst switches that are used to simulate binary values: 0000 or 1000 etc.
What I want to do is make another part of this circuit that can simulate counting in binary for me up to X values. This way I can plug in the switches to the digital output and maybe press a switch to increment through the truth table.
I was thinking I could use the onboard 555 timer and use that somehow but I am lost.
