Connect a Raspberry Pi to a KY-034 7 color flashing LED

Parts Required

You can connect to the module using dupont style jumper wire. There is no reason this device will not work with any Raspberry Pi hardware that you have – in this example a Raspberry Pi 4 but you can use a Zero if you want a lower cost solution

Code Examples

Basic example in  thonny, running on the Raspberry Pi

import RPi. GPIO  as  GPIO
import time
  
GPIO.setmode (GPIO.BCM) 
  
# The input pin
LED_PIN = 24
GPIO.setup(LED_PIN, GPIO.OUT, initial= GPIO.LOW)
  
print ("Flashing LED test [press CTRL+C to end the test]")
 
# Main program loop
try:
    while True:
        print("LED 4 seconds on")
        GPIO.output(LED_PIN,GPIO.HIGH) # LED is switched on
        time.sleep(4)  # Wait for 4 seconds
        print("LED 2 seconds off") 
        GPIO.output (LED_PIN,GPIO.LOW) # LED is switched off
        time.sleep (2)   # LED is switched off
 
# Tidying up after the program is finished
except KeyboardInterrupt:
    GPIO.cleanup ()
