About this model

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 (vertical) movement of the solar panel. ☀️ Solar Charging & Battery System The project also includes a DD05CVSA 5V charging/discharging module. The solar panel is connected to the DD05CVSA module, which is used to charge the 3.7V lithium-ion batteries and provide a regulated 5V output. This means th…
