Aim

• To interface an incremental encoder with an Arduino Uno to measure the speed (RPM)of a DC motor .

Objective

• Understand the working of an incremental rotary encoder
• Interface the encoder with Arduino UNO using digital input pins
• Learn to use an interrupt-driven approach in Arduino to count encoder pulses accurately and efficiently.
• Program the Arduino to measure the encoder pulses to display the motor RPM based on counted pulses.
