Introduction

In this lesson, we can make the RGB LEDs light up the colors we want and even make color loops.

Components

Programming Steps

Step 1

Create a new project, then click on the Simulation icon on the left side of the page to enter the Simulation page.

Step 2

Drag the RGB LED module to the Simulation area, then connect the R, G and B pins to P2, P1 and P0 respectively in Ezblock Pi. And connect the VCC to 3.3v.

Step 3

Go back to the Programming page, then drag out the RGB module block under the Sensor Kit category, and put it into the Forever block select the color we want.

Step 4

Then go to the Simulation page again; click on the run icon, and we can see the RGB LED module showing the corresponding colors.

Step 5

Use the delay block from Basic category to keep RGB LED module in this color for 1000 milliseconds (1second).

Step 6

Long press RGB module block and then click Duplicate to copy 2 identical RGB blocks.

Step 7

Choose the color we want. Now we can make the RGB LED module blink different colors.

Step 8

Enter the Simulation page again to see the effect. Now save your project, connect the Bluetooth and click Flash to compile and download the code.
