KY-034 AUTOMATIC FLASHING COLOR LED

The KY-034 fea­tures a 7 col­or LED that flash­es through a sequence of col­ors, cre­at­ing a mul­ti­col­ored pat­tern of flash­ing light. The sequence is pre­de­fined and can­not be mod­i­fied.This mod­ule can be used in dec­o­ra­tive projects, and it is com­pat­i­ble with Arduino, ESP32, Rasp­ber­ry Pi, ESP8266, and oth­er pop­u­lar micro­con­troller boards. SPECIFICATIONSWork­ing volt­age3V — 5V DCLED mod­elYB-3120B4P­nYG-PMLED type5mm round headBoard Size16.5mm x 18.5mm [0.65in x 1.73in] CONNECTION DIAGRAMCon­nect the KY-034’s sig­nal pin (S) to pin 13 on the Arduino, then con­nect the ground pin (-) to GND.The mid­dle pin and the (-) pin on the KY-034 are con­nect­ed, and they both act as ground. You only need to con­nect one of the pins to GND on the Arduino.Keep in mind that there are sim­i­lar mod­ules with a dif­fer­ent pin con­fig­u­ra­tion. Always check the pins before con­nect­ing your board.KY-034 ARDUINO CODEIn the fol­low­ing sketch, we’ll use the pin 13 on the Arduino to repeat­ed­ly turn the LED on the mod­ule on for 3 sec­onds and off for a sec­ond. int ledPin = 13; // pin to control KY-034 void setup() { pinMode(ledPin, OUTPUT); // define pin as output } void loop() { digitalWrite(ledPin, HIGH); // turn LED on delay(3000); // wait for 3 seconds digitalWrite(ledPin, LOW); // turn LED off delay(1000); // wait for a second }12345678910int led­Pin = 13; // pin to con­trol KY-034void set­up() { pin­Mode(led­Pin, OUTPUT); // define pin as out­put } void loop() { dig­i­tal­Write(led­Pin, HIGH); // turn LED on delay(3000); // wait for 3 sec­onds dig­i­tal­Write(led­Pin, LOW); // turn LED offdelay(1000); // wait for a sec­ond}  DOWNLOADS http://• Fritz­ing Part: KY-034 Auto­mat­ic Flash­ing Col­or LED
