Solar Powered Charging Station

For my final project I would like to engage in a solar powered charging station that could provide an output of a usb slot made for devices to power up.

The initial idea is to be able to have a solar panel that could automatically position it self according to where the sun is facing at any given moment. Its rotation should be done on the Y-axis as well as the X-axis.

What will be needed at a first glance:

– Arduino Uno
– Solar panel
– Servo
– Light Detecting Resistors
– Wooden/Acrylic Box (Laser Cut)
– USB output

The first step was to determine its part that its going to be used individually in order to see if everything works as it should:

Some testing with the servo motor:

Some testing with the Light Detecting Sensors:

Combining the Servo with the Light Detecting Sensors:

Having successfully operated the sensors with the servos the next step is to start building the enclosure for the Arduino and the electrical components as well as the structure for the panel and servos to operate:

The initial testing is being done with cardboard in order to ensure that everything can work proportionally and mechanically correct before proceeding to wood and acrylic.

The next step is to finalize the design and make sure that everything fits together properly.

Lasercutting the necessary pieces to form the structure of the solar panel:

Checking various pieces to see how they fit together:

Testing for Voltage and Amps:

The problem is that the battery produced around 2V which is not enough to power the Arduino board and run it. The o.43 Amps that the motors and sensors with the Arduino produced where a positive sign.

Finally some testing was done to see how the sensors reacted to the light and how they could accurately track it. There is difference in the behavior of the sensors when there is more light around them rather than having them in a darker room with direct light focusing on the sensors only.
