A joystick module is used to perform functions on a 16x2 LCD screen.
The first implementation of this project dealt with outputing ASCII characters onto the Liquid Crystal Display (LCD) screen. The joystick module uses potentiometers and a push button. The X-axis potentiometer was used to control the cursor on the LCD screen. The Y-axis potentiometer was used to increment or decrement through the ASCII character values. The push button in the joystick was used to clear the screen and reset the cursor position.
Materials: Arduino Uno, Joystick module, 220 Ω resistor, 10 KΩ rotary pot, and wires.
