Interfacing 2-color led module with evive

About This Tutorial

In this tutorial we will interface 2-color led module with evive and we will produces different color combination’s using this led

Tutorial Info

Programming Platform: Arduino IDE
Difficulty: Beginner
Estimated Time: 1 Hrs
LED, PWM

Components Required

Component	Quantity	Available in Kit
evive	1	evive
USB A-B Cable	1	evive
Male to Female Jumper Cable 10cm	1	None

Introduction

The KY-011 2-color led is a handy littel component that allows two colors ( Red and Green) in a single LED while only having 3 pins

Comman cathode pin
Anode for green led
Anode for red led

The KY-011 2-color led emits red and green colors but by applying different voltages on anodes of led we can produce different colors ,we will use PWM pin’s of our evive board to generate different voltages ,click here for more information on PWM

Circuit diagram

Connect comman cathode pin of KY-011 module to ‘GND’ pin of evive
Connect anode of green LED to pin number 10 of evive
Connect anode of red LED to pin number 11 of evive

Arduino code

We have used two different ‘for’ loops in this code , first for loop will increase the intensity of “Red” led and second ‘for’ loop will increase the intensity of “Green” led

Expected result
