description 1 3 Pinout 2 4 Code example Arduino 2 5 Code example Raspberry Pi 3 Picture Technical data / Short description If you connect this module with a power supply, a LED will light up which changes its colour automatically. It includes 7 different colours. Voltage range: 3,3V - 5V Export: 16.06.2017 Copyright by Joy-IT - Published under CC BY-NC-SA 3.0 Page 151 of 214 KY-034 7 Colour LED flash-module Pinout Code example Arduino This code example shows how you can switch a LED on for 4 seconds and than off for 2 seconds via defined output pin. int Led = 13; void setup () { pin Mode (Led, OUTPUT); // Initialization of the LED output pin } void loop () // main program loop { digital Write (Led, HIGH); // LED will be switched on delay (4000); // waitmode for 4 seconds digital Write (Led, LOW); // LED will be switched off delay (2000); // waitmode for another 2 seconds } Connections Arduino: Sensor Signal Sensor [N.C] Sensor GND = [Pin 13] = = [Pin GND] Example program download: KY-034_7-color-led-flash-module Export: 16.06.2017 Copyright by Joy-IT - Published under CC BY-NC-SA 3.0 Page 152 of 214 KY-034 7 Colour LED flash-module Code example Raspberry Pi # Needed modules will be imported and configured import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) # Declaration of the input pin which is connected with the sensor. # Additional to that the pull up resistor from the input will be activated.
