Introduction: Simple Solar Tracker

This a demonstration of solar tracker controlled by arduino board.

Tracker position is determined by comparing voltage drops across two photoresistors.

Step 1: Tracker Components

For this simple 1D solar tracker, we need for:

1. Arduino board.

2. Two photoresistors.

3. One servo-motor.

4. Solar cell/mini-module.

Step 2: Construction of Voltage Dividers

The solar sensor in our case is a simple two voltage dividers.

Construct a two voltage dividers using one photoresistor and a 10k resistor each.

Than, mounting this sensor on a Servomotor.

Step 3: Arduino Code

Attach Sensor outputs to Arduino board analog input A0 and A1.

Attach Servo signal wire to digital pin 9.

Upload the code and go on!

Fun project. I did something similar for my senior design project in school.
