Demo
- Press PB1 once quickly, and the LED's will begin to light in order, going from LED1-LED4 before restarting at LED1 again. Each time the LED's cycle, the REPL connection will display the number of cycles. Press PB1 again to stop the cycle.
- Hold PB1 for a second, and the same thing happens, except this time the LED's cycle in reverse from LED4-LED1. Press PB1 again to stop the cycle.
