Unassembled DIY Dual-Axis Solar Tracker Kit

Introduction to Dual-Axis Solar Tracker

The Dual-Axis Solar Tracker Arduino Kit is an educational DIY project that demonstrates how a solar panel can automatically follow a light source. Moreover, the system combines an Arduino Uno, two SG90 servo motors, four LDR modules, and a 400-hole breadboard to create a two-axis tracking mechanism. In addition, the unassembled design lets learners build the system themselves and understand how its mechanical and electronic parts work together. As a result, it provides a practical introduction to solar tracking and Arduino-based automation.

How the Dual-Axis Solar Tracker Works

The tracker uses four LDR modules to detect differences in light intensity from different directions. First, the LDRs sense changes in available light and send signals to the Arduino. Next, the Arduino compares the sensor readings to identify the direction with stronger light. Then, it sends control signals to the two SG90 servo motors. Consequently, one servo adjusts the horizontal position, while the other changes the vertical position.Furthermore, users can assemble the tracker components, connect the wires according to the circuit design, upload the Arduino program, and test its movement. If necessary, they can also adjust the resistor values according to different lighting conditions. Therefore, the project combines light sensing, programming, and motor control in one hands-on system.
