This report describes the design of the "Solar Powered LED street Light with auto intensity control" The project based on two modules. 1. Charge controller circuit. 2. Load intensity control circuit. Using 18v solar panel we will charge 12v battery. The charge controller circuit can prevent the battery to flow high current through it after that we will convert 12v to 5v using voltage regulator circuit. Using Light dependent resistor (LDR) we check its resistance with the help of sunlight, and

... e output of LDR is given to analog read pin of Arduino To perform PWM we can generate different analog voltages using Arduino UNO software. The circuit of the project is designed, simulated and built with hardware. The simulation results and design details are provided. Circuit diagram of our project is successfully tested on hardware
