Tutorial: How to use the 3W/2W PWM LED Module (700mA, 5-35V)
This module is perfect for controlling powerful LEDs with Arduino. It uses PWM to regulate the intensity.
What you need
- Arduino
- Compatible LEDs
- jumper cables
Steps
- Connect the module pins to the Arduino output pins.
- Check the power supply voltage (5-35V) and connect the power adapter.
- Configure the PWM on the Arduino pin used to control the light intensity.
- Test the functionality with a simple sketch that gradually changes the LED brightness.
Example code
const int pwmPin = 9;
void setup() {
pinMode(pwmPin, OUTPUT);
}
void loop() {
analogWrite(pwmPin, 128); // Imposta il PWM a metà intensità
}
Mini project
Create a controllable lighting system using Arduino and this LED module.
Common mistakes
- Connect the power supply voltage outside the allowed range.
- Do not properly configure the PWM pin in Arduino.
Recommended accessories
- Power supply protection module
- Light sensors
