The Atmega328 microprocessor, on which the system is built, cleverly detects and charges the battery while showing the voltage on the LCD. The windmill can provide enough electricity to charge a battery when there is sufficient wind to propel it.

Similar to this, the solar panel, which is fixed to a revolving panel and adjusts for maximum exposure to the sun, may provide energy sufficient to recharge the battery. Both of them can charge the battery more quickly than they could separately since they can both work in ideal outside circumstances simultaneously.

Thus, this project serves as an illustration of how natural resources may be effectively used to create power more quickly and cheaply.

• Solar UPS Project:

This project is a solar-powered UPS that uses solar energy to charge a battery before using the DC battery and an inverter to power an AC load. Using charge controller circuitry, our solar panel continuously charges the 12V DC battery. And as soon as the load switch is activated, the battery charge is reversed and increased from 12 V DC to around 140–150 V AC.

The AC load is now given thus. As a result, our system uses a solar panel and battery to successfully power an AC load.

• Scare mosquitos using Solar:

This solar-powered gadget gets rid of mosquito larvae in marshes and other stagnant water areas. Due to the system, mosquitoes may deposit their eggs at dawn and dusk, while throughout the day, the sporadic ripples prevent larvae from breathing at the surface.

Additionally, an integrated microphone records the wing-beat frequencies of mosquitoes that are drawn to standing water naturally, which aids in determining the species and sex of the insect. We will get a real-time estimate of the number of hazardous mosquitoes by installing a network of these linked devices among at-risk communities.
