Diagram (click to enlarge) This is non-interrupt reset pin model.
Code here: (Note, you need to download the new soft serial library for this counter) Also, this code hasn't been changed to the interrupt on the reset pin. I've coded that but need to test it, so here the reset button is not an interrupt.
I will be working to better document this code so it's more clear.
