☀️ Solar Tracker Circuit Connections

🔌 Arduino to Servo Motor

• Red wire → 5V

• Brown/Black wire → GND

• Yellow/Orange wire → Digital Pin 9

🌞 LDR Sensor 1 (Left Sensor)

• One leg → 5V

• Other leg → Analog Pin A0

• Connect a 10kΩ resistor between A0 and GND

🌞 LDR Sensor 2 (Right Sensor)

• One leg → 5V

• Other leg → Analog Pin A1

• Connect a 10kΩ resistor between A1 and GND

⚙️ How It Works

• The two LDR sensors detect light intensity.

• Arduino compares readings from both sensors.

• The servo motor rotates toward the side with higher light intensity.

• This allows the system to continuously track the sun.

💡 Pro Tip (Important)

Place a small barrier between the two LDRs to improve accuracy in detecting light direction.

Here, I encountered a problem where the servo motor unfortunately refused to rotate. I suspect there is an internal mechanical issue with the servo, as I tried connecting it directly to a 5V supply, but it still did not work. It only produced a very faint sound that was barely audible.
