Easy Solar Tracking System Using Arduino.

In a modern solar tracking system, a solar panel device detects the sun power in which direction it is coming from. The solar tracker is a tracking device that tracks sun power and changes its direction according to it. This is a fixed device that is flexible towards the light. The circuit seems to be easy but the setup can be a bit complicated. So it has to be done carefully. Today I will show step by step how you can make a solar tracker yourself.

You need

1. Arduino UNO

2. LDR

3. Light sensors

4. Servo motor

5. Resistors

The Setup

Step-1 First, you have to take a cardboard and make a hole in the middle and four holes on four sides to fit LDR into that. Then stick the solar panel to the cardboard and bring two wires of the panel out as shown in the picture.

Step 2 Now you have to cut one lead of the LDR and that one lead must be shorter than the other one. Insert these four LDRs into 4 side corner holes. Bend the straight Perforated metal strip as shown in the picture and place the bent metal strip on the backside of the cardboard. Apply glue to the LDR to place them.

Step 3 Solder the two leads of LDR as shown and to the other ends of LDR solder resistors of 10k ohm. Connect the 4 LDRs with a wire.

Step-4 Now you have to take a bus wire. This will help to connect the outputs of four LDRs to the Arduino board. Now insert it into the metal strip as shown in the picture. Now you have to solder the four wires to four LDRs between LDR and resistor.

Step 5 You have to insert another two-wire bus into the perforated metal strip for supplying Vcc and GND to the LDR circuit one wire leads to the LDRs which are connected to resistors and the other wires to the other leads. You have to shorten the leads of LDRs connected to resistors using a wire as shown in the picture.

Step 6 Now comes the motor part. You have to connect a servo motor to the perforated metal strip. Apply glue to the servo to keep it in place. Take another straight perforated metal strip and bend it.

Step-7 Now the last part. Place the set up of solar panel and first servo motor to the metal strip of the second servo motor as shown in the picture. And you are all done.
