Mix Colors on the RGB LED Lights

Use the ‘Parts List’ image along with the component cards in your box to correctly plug in the electronic hardware to your Maker Board. The colorful dots next to the legs of the components match up to the ports where that leg should go on Maker Board’s ports.

Code

The code in the editor below is ready to run! Plug in the electronic components just like the Parts List card above, connect Maker Board to your computer's USB port with the cable, and hit 'Upload Your Code!'. Tinker with the code and change something! If you get stuck, you can hit the 'Restore' button to make the code go back to the working example.


/* Power multiple legs of the multicolor (RGB) LED light on and off to create blended colors */ void setup(){ pinMode(2,OUTPUT); //set the 2,3,and 4 ports to receive power pinMode(3,OUTPUT); pinMode(4,OUTPUT); } void loop(){ digitalWrite(2,HIGH); //turn on the LED color whose leg is plugged into port 2 delay(1000); //Wait 1000 milliseconds (1 second) with only one color on. digitalWrite(3,HIGH); //turn on a second color using port 3 delay(1000); //Wait 1000 milliseconds digitalWrite(4,HIGH); //turn on a third color using port 4 delay(1000); //Wait 1000 milliseconds digitalWrite(2,LOW); //turn off the first color on port 2 delay(1000); //Wait 1000 milliseconds digitalWrite(3,LOW); //turn off the second color on port 3 delay(1000); //Wait 1000 milliseconds digitalWrite(4,LOW); //turn off the third color on port 4 delay(1000); //Wait 1000 milliseconds before starting the loop over } // (c) 2019 Let's Start Coding.
