Arduino PWM Motor Speed Control Kit with Encoder Feedback & LCD

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Build a closed-loop motor speed controller that maintains precise RPM under varying load — a foundational skill for robotics and automation. Wire the L298N and LM393 encoder to an Arduino Uno, program a PID algorithm, and display real-time RPM on a 16x2 LCD. This kit replaces scattered tutorials with a curated path where every component is guaranteed compatible.

What You'll Build

Assemble a DC motor control system that automatically adjusts PWM to hit a set RPM target. The encoder counts shaft slits, Arduino computes error, and the LCD shows setpoint and actual speed — a feedback loop you can tune, just like in drones and CNC machines.

What You'll Learn

• Tune a PID controller (proportional, integral, derivative) to stabilize motor speed under changing load
• Interface an LM393 optical encoder to count pulses and calculate RPM in code
• Drive a 12V DC motor through an L298N H-bridge with Arduino PWM
• Display real-time sensor data on an I2C 16x2 LCD – no extra wiring complexity
