RGB LED Module – Common Cathode 10mm

Description

What is the Common Cathode RGB LED Module? The Common Cathode RGB LED Module is an electronic component suitable for various RGB lighting projects. This module is ideal for adding multicolour lighting effects to your Arduino or ESP projects. Features – Common Cathode RGB LED Module – Compatible with Arduino and ESP – Enables creation of multicoloured lighting effects Use Cases Ideal for projects requiring precise control over RGB lights, such as controllable chandeliers using the Android or iOS app Arduino Remote. Tutorial: How to use the 10mm Common Cathode RGB LED Module This versatile component is perfect for beginners and makers looking to add multicolour lighting effects to their projects. What you need – Arduino Uno – Jumper wires – Battery USB – Resistors Steps Connect the battery’s positive voltage to the VCC pin of the LED module. Connect the battery’s ground to the GND pin of the LED module. Use jumper wires to connect the data pins of the LED module to digital pins on the Arduino. Check the datasheet for the correct resistor value to limit current at the data pins. Write an Arduino sketch to control the LED module. Upload the sketch to the microcontroller. Test the LED module by changing its colour. Add a button to control the LED module (optional). Example Code void setup() { pinMode(9, OUTPUT); pinMode(10, OUTPUT); pinMode(11, OUTPUT); } void loop() { analogWrite(9, 255); analogWrite(10, 0); analogWrite(11, 0); delay(1000); analogWrite(9, 0); analogWrite(10, 255); analogWrite(11, 0); delay(1000); analogWrite(9, 0); analogWrite(10, 0); analogWrite(11, 255); delay(1000); } Mini Project Create an RGB chandelier controllable with an Android or iOS phone using the RGB LED module and Arduino Remote app. Common Mistakes Not verifying correct resistor values for data pins. Connecting negative voltage to ground. Proceeding without testing the LED module’s functionality first. Using a power supply voltage higher than the maximum limit of the LED module. Recommended Accessories – Variable resistors – Buttons – Arduino Nano – USB B cable
