Introduction

Arduino Input Shield

The Arduino Input Shield includes a two axis mini joystick (with moment switch) as well as two colored push buttons. The reserved APC220 Radio Data Module(SKU:TEL0005) interface is to facilitate the realization of wireless rocker button controller. The shield can be easily stacked on top of your Arduino.
