![]() And we can get the direction of movement by interpreting these voltage changes using some microcontroller. This Joystick module typically provides Analog Outputs and the output voltages provided by this module keep changing according to the direction in which we move it. A typical Joystick module is shown in the figure below. Joysticks are available in different shapes and sizes. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.ģ2 KB (ATmega32u4) of which 4 KB used by bootloader The Leonardo is different from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 20 digital input/output pins (out of which 7 can be used as PWM outputs and 12 as Analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header and a reset button. Arduino Leonardo has advantage over Uno that we can install USB drivers on it and it can be detected as mouse, keyboard or joystick by computer when connected.įor this project we are using the Arduino Leonardo, it is a microcontroller board based on the ATmega32u4. ![]() Here we will use Arduino Leonardo to interface Joystick as Game controller. To play games which requies more control options, two or more joysticks can be used. In this project we will use the same Joystick as Gamepad or game controller to play any computer games which requires left, right, up and down movements. We previously interfaced Joystick with Arduino UNO to understand how it works and controlled four LEDs on its left, right, up and down movement.
