Lesson 13 Analog Joystick Module
Overview
Analog joysticks are a great way to add some control in your projects.
In this tutorial we will learn how to use the analog joystick module.
Component Required:
(1) x Elegoo Mega2560 R3
(1) x Joystick module
(5) x F-M wires (Female to Male DuPont wires)
Component Introduction
Joystick
The module has 5 pins: VCC, Ground, X, Y, Key. Note that the labels on yours may
be slightly different, depending on where you got the module from. The thumb stick
is analog and should provide more accurate readings than simple ‘directional’
joysticks tact use some forms of buttons, or mechanical switches. Additionally, you
can press the joystick down (rather hard on mine) to activate a ‘press to select’ push-
button.
We have to use analog Arduino pins to read the data from the X/Y pins, and a digital
pin to read the button. The Key pin is connected to ground, when the joystick is
pressed down, and is floating otherwise. To get stable readings from the Key /Select
pin, it needs to be connected to VCC via a pull-up resistor. The built in resistors on
the Arduino digital pins can be used. For a tutorial on how to activate the pull-up
resistors for Arduino pins, configured as inputs
