2mm Bicolor Red Green LED Module KY-029 Compatible with Arduino

Description

The 2mm Bicolor Red Green LED Module KY-029 is an electronic component compatible with Arduino that allows the use of two different colors (red and green) on a single unit. This module is ideal for projects requiring simple yet effective visual indications. Features: Compatible with Arduino and other similar microcontrollers. Purpose: Ideal for lighting projects, indicators, or visual signals. Can be integrated into devices such as LED clocks that change color at regular intervals. How to use: Connect the VCC and GND pins of the KY-029 module to +5V and GND of the Arduino respectively. Connect the D1 pin (or any other) of the module to the single available digital interface on the opposite side of the LED module. Upload the sketch to Arduino to control the module. Ensure the correct current direction: red towards +5V, green towards GND. Change the logical state of the digital interface (HIGH or LOW) in code to change the LED color. Example code: void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); // Turn on red delay(500); digitalWrite(13, LOW); // Turn off red and turn on green delay(500); } Mini-project: Create a simple LED clock that changes color at regular intervals. Common errors: Incorrect connection between Arduino and KY-029, Incorrect pin configuration in code, Incorrect LED module polarity. Recommended accessories: USB Type B Cable, Arduino Uno or compatible, Arduino project base kit. Frequently asked questions: How does the color change? The color changes when the logical state of the pin connected to the module is modified. Can I use other colors? This module supports only red and green. Check the datasheet for other options.
