KY-034 7 Color flash-LED

This module contains a 7-color flash LED that automatically emits a sequence of color changes as soon as it is supplied with voltage. The LED has 7 different colors and can produce all resulting mixed colors. This module is ideal for decorative lighting projects, visual displays and effects where changing colors are desired. The automatic color sequence means you don't need any additional control, making it easy to integrate into different projects. It is perfect for creative applications where dynamic and appealing lighting is required.

Code example

This code example shows how an LED can be switched on for four seconds and then switched off for two seconds by means of a definable output spin.

To load the following code example onto your Arduino, we recommend using the Arduino IDE. In the IDE, you can select the appropriate port and board for your device.

Copy the code below into your IDE. To upload the code to your Arduino, simply click on the upload button.

int led = 13; // Declaration of the LED input pin
 
void setup() {
  pinMode(led, OUTPUT); // Initialization output pin for the LED
}
 
void loop() {
  digitalWrite(led, HIGH); // LED is switched on
  delay(4000); // Wait for 4 seconds
  digitalWrite(led, LOW); // LED is switched off
  delay(2000); // Wait for another two seconds
}

from gpiozero import LED
import time

# Initialization of the LED
led = LED(24)

print("LED test [press CTRL+C to end the test]")

# Main program loop
try:
    while True:
        print("LED on for 4 seconds")
        led.on()  # LED is switched on
        time.sleep(4)  # Wait mode for 4 seconds

        print("LED off for 2 seconds")
        led.off()  # LED is switched off
        time.sleep(2)  # Waiting mode for a further two seconds, during which the LED is then switched off

# Clean up after the program has been completed
except KeyboardInterrupt:
    print("Program was interrupted by user")
    # gpiozero automatically takes care of the cleanup when the program is interrupted

		    pins.digitalWritePin(DigitalPin.P1, 1)

		input.onButtonPressed(Button.B, function () {
		    pins.digitalWritePin(DigitalPin.P1, 0)
		})
