Dual-Axis Solar Tracker with Arduino (USB Power)

This project is a 3D-printed dual-axis solar tracker designed to automatically follow the direction of the strongest light and improve the positioning of a solar panel throughout the day. The system uses four LDR light sensors to detect differences in light intensity. An Arduino Nano continuously compares the sensor readings and controls two 28BYJ-48 stepper motors through ULN2003 driver boards. One motor controls the left-right (horizontal) movement, while the second motor controls the up-down…
