ARDUINO JOYSTICK WITH BUTTON SHIELD​

Features:

The Joystick Shield enable your Arduino with a joystick! The shield sits on top of your Arduino and turns it into a simple controller. Five momentary push buttons (4+ joystick select button) and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers.
This shield is a great piece of uer interface board, it is perfect for gaming and navigating through menu quickly. It has headers for LCDs and RF modules , to communicating and displays easily.
