8-bit binary counter which displays as LED high output.
To run the code, simply fork the repo, download the .ino file and upload it to your own Arduino (or equivalently C driven micro-controller.)
Number of iterations of counting is delimited by how many LEDs one has hooked up to the circuit.
For instance, this 8bit counter only counts to 256 in binary (2^# of LEDs), but the code and circuit could easily be modified to accomodate a higher count cieling.
