Rotary Encoder

The Rotary Encoder project demonstrates how to use an Arduino Nano to read the rotation direction of a rotary encoder. Rotary encoders are input devices that convert the angular position or rotation of a shaft into digital signals. This project interprets the signals from the rotary encoder and prints the rotation direction to the Serial Monitor.

Components Needed

• Arduino Nano
• Rotary Encoder
• Jumper Wires

Circuit Diagram

Circuit Setup

1.Connect Rotary Encoder to Arduino Nano:

CLK Pin: Connect to digital pin 2 (D2) on the Arduino Nano.

DT Pin: Connect to digital pin 3 (D3) on the Arduino Nano.

Instructions

1.Circuit Setup:

Wire the rotary encoder to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Open the Arduino IDE and paste the provided code.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, open the serial monitor.

Rotate the encoder clockwise and counter-clockwise.

The serial monitor will display the rotation direction.

Applications

User Input Control: Use rotary encoders as input devices for controlling parameters such as volume, menu selection, and scrolling in various electronic projects.

Interface Design: Implement rotary encoders as user interface elements for navigating menus and adjusting settings in devices.

Position Sensing: Utilize rotary encoders for position sensing applications in robotics and automation.

Notes

Ensure the rotary encoder is securely attached and correctly wired to the Arduino Nano.

Adjust the CLK and DT pin assignments in the code if you connect the rotary encoder to different digital pins.

Experiment with different types of rotary encoders to suit the specific requirements of your project.
