2 Axis Solar Tracker Circuit

Description: The sun trucker employs three photoresistors, R7, R8, and R9, to enable the circuit to track the sun during daylight hours while ceasing operation at night. Additionally, the circuit can be duplicated to achieve movement along four axes by utilizing two motors.

The sun trucker circuit is designed to harness solar energy effectively by utilizing a photoresistor-based tracking mechanism. The three photoresistors, R7, R8, and R9, are strategically placed to detect the intensity of sunlight from different angles. This arrangement allows the circuit to determine the direction of the sun's position in the sky.

When the sun's light hits the photoresistors, the resistance changes, generating a variable voltage output that can be read by a microcontroller or comparator circuit. The microcontroller processes the readings from the photoresistors and determines which direction the motors should move to align the solar panel with the sun. This alignment optimizes the panel's exposure to sunlight, thereby maximizing energy collection.

To enhance the system's capabilities, the circuit can be duplicated, allowing for movement along four axes. This is achieved by incorporating two motors, each responsible for controlling the movement in a specific axis. The first motor can control the azimuthal movement (left and right), while the second motor can handle the elevation (up and down) of the solar panel.

The circuit should also include a light-dependent resistor (LDR) or a similar mechanism to detect low light levels, which will trigger the motors to stop their operation at night. This feature is essential to prevent unnecessary wear on the motors and to ensure energy efficiency.

In summary, the sun trucker circuit is a sophisticated system that utilizes photoresistors for solar tracking and can be expanded for multi-axis movement through the addition of motors, making it an effective solution for maximizing solar energy capture.The sun trucker uses a combination of three photoresistors R7, R8 and R9, to ensure that the circuit will follow the sun during the day, but stop working at night time. Make this circuit 2 times to have 4 Axis move, by using 2 motors.
