This is a Fritzing file showing how I connected to the Esplora's Tinkekerkit connectors to a breadboard with 4 buttons.
Esplora sketch that reads the Tinkerkit connectors and sends the values to the serial monitor for testing.
Esplora sketch that makes the Esplora a MAME controller with 4 extra buttons connected to the Tinkerkit connectors for: Escape, Enter, Start(1), Add Credit(5).
