Description
Shield forArduinowith popular 2x16 character LCD display and with five buttons at the user's disposal. It offers 16 million color combinations. The screen uses pins 4, 5, 6, 7, 8, 9 and 10. Reading the button's state occurs through an analog signal, thanks to this solution, all five buttons uses only one A0 lead. The 5 V supply voltage comes from the Arduino.
