Rotary Encoder Project

The Rotary Encoder project demonstrates how to interface a rotary encoder with an Arduino Mega to detect rotational movements and button presses. Rotary encoders are useful for applications where precise rotational control or user input is required.

Circuit Setup

Connecting the Rotary Encoder to Arduino Mega:

Instructions

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud).

Rotate the rotary encoder clockwise and counterclockwise.

Press the encoder switch to see "Switch pressed!" messages.
