Arduino is an open-source electronics platform that allows input from sensors and output to devices like motors or displays. It has advantages like being inexpensive, cross-platform, with easy programming. A solar mobile charger works by collecting solar energy from panels and storing it in a battery to charge phones through USB ports, providing off-grid charging. It has panels to absorb sunlight, a battery to store energy for later, and ports to charge devices. The amount charged depends on sunlight exposure and panel capacity. Solar charging saves energy and uses renewable sources for portable, environmentally friendly phone power.

3. WHAT IS ARDUINO
Arduino is an open-source electronics platform based on
easy-to-use hardware and software. Arduino gets its input
from a sensor and sensor can be any kind, or it can also be a
buttons etc.. The output is obtained on to a motor or LED
display, a notice board etc.. we can send set of instructions to
the microcontroller on the board. Arduino is a programming
language and processing is based on Arduino software IDE.

6. Solar mobile charger works on the solar energy where . solar energy is
collected directly from the sun and electric current is produced. This
energy is utilized to change the mobile. It works similarly as a normal
charger.
A solar mobile phone charger is a device that uses solar panels to
convert sunlight into electrical energy, which can then be used to charge
a mobile phone or other electronic devices. It provides a convenient and
eco-friendly way to charge your phone, especially when you're outdoors
or in areas without access to electrical outlets

WORKING OF SOLAR CHARGER

9. Solar Panels: The charger is equipped with one or more solar
panels made up of photovoltaic cells. These cells absorb
sunlight and convert it into direct current (DC) electricity.
Battery : Many solar chargers have a built-in battery or
power bank. The solar panels charge the battery during
daylight hours, storing the electrical energy for later use. This
allows you to charge your phone even when there's no
sunlight available.

10. Charging Output: The charger typically has one or more
USB ports or other charging connectors. You can connect
your mobile phone or other devices using the appropriate
charging cable.
Sunlight explosure: To charge your phone, you need to
expose the solar panels to sunlight. The efficiency of the
charger depends on the amount of sunlight available and
the capacity of the solar panels.

12. CONCLUSION
It’s important to note that solar chargers may take longer to charger
your phone compare to traditional Electrical outlets, especially if sun
light is limited or the charger as lower voltage. however they provide
a Convenient and environmentally friendly charging option . Using
solar mobile charger can save the energy and we will be using
Renewable energy and its portable , environmentally friendly
solution for charging the Phone . Thus helps humans to walk towards
sustainable development.
