Tutorial: How to Use Small Solar Panel

This small solar panel is ideal for powering low-power projects such as sensors, LEDs, or microcontrollers. Perfect for beginners and makers who want to explore solar energy.

What you need

• Arduino Uno
• JST Cable
• Resistor

Steps

1. Connect the solar panel to the JST cable
2. Check the panel’s output voltage with a multimeter
3. Connect the other end of the JST cable to an Arduino power port
4. Write and upload a simple sketch to control the battery level
5. Verify correct function by connecting an LED to an output port

Example code

//Sketch Arduino
int ledPin = 13; // Collega l'LED al pin 13
void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  digitalWrite(ledPin, HIGH); // Accendi il LED
  delay(500); // Attendi per 500ms
  digitalWrite(ledPin, LOW); // Spegni il LED
  delay(500); // Attendi per 500ms
}

Mini project

Build a light sensor that automatically turns on an LED when sunlight fades.

Common mistakes

• Do not verify the correct output voltage before use
• Connect the solar panel directly to devices without protection
• Use an incompatible or damaged JST cable

Recommended accessories

• LiPo Battery 3.7V 1000mAh
• TP4056 Battery Holder with Prototype
• JST M-M Cable
• Light Sensors LDR
