Automate Street Lighting with Arduino Uno and LDR — Build a Sun-Tracking Solar Panel System

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

Cities run streetlights on crude timers. What if a streetlight could sense darkness, turn on, and even orient its solar panel to catch maximum sunlight during the day? This kit lets you build a proof-of-concept street light that uses four LDRs to track ambient light, a servo to position a solar panel, and an INA219 to compare power output with a fixed panel.

What You'll Build

A working model of a smart street light that automatically switches on at dusk, plus a solar panel alignment system that follows the brightest point in the sky. The OLED displays real-time voltage, current, and power, while the servo adjusts the panel angle to maximize energy harvesting. You’ll end with hard data showing how much more power a tracking solar panel produces over a stationary one.

What You'll Learn

• Calibrating light-dependent resistors as a quad-sensor array for directional ambient light detection.
• Programming Arduino Uno to read multiple analog inputs and drive servo motors for precise solar panel positioning.
• Using INA219 current sensor to measure real-time voltage, current, and power, and comparing tracking vs. fixed-panel performance.
• Interfacing an OLED display to visualize sensor data and debug embedded system output.
