Sending & Receiving Data with the Serial Monitor

Task 2: Coding in the IDE

Now it's time to write code using the Arduino IDE. Let’s break it down into steps:

Name your sketch.
Create space for your variables.
Define those variables.
Use pinMode in void setup to set up your pins.
Use digitalWrite in void loop to control the LED.

Follow along with the code in the image below!



            // Lesson 5
            // Variables
            // Serial monitor must be set to "NO LINE ENDING"
            
            int redPin = 3;
            int greenPin = 5;
            int bluePin = 6;
            
            int dtGreen = 500;
            int dtBlue = 1000;
            int dtRed = 1500;
            
            void setup() {
              // put your setup code here, to run once:
              pinMode(redPin, OUTPUT);
              pinMode(greenPin, OUTPUT);
              pinMode(bluePin, OUTPUT);
            }
            
            void loop() {
              //put your main code here, to run repeatedly:
             
            
              digitalWrite(greenPin, HIGH);
              delay(dtGreen);
              digitalWrite(greenPin, LOW);
              delay(dtGreen);
            
              digitalWrite(bluePin, HIGH);
              delay(dtBlue);
              digitalWrite(bluePin, LOW);
              delay(dtBlue);
            
              digitalWrite(redPin, HIGH);
              delay(dtRed);
              digitalWrite(redPin, LOW);
              delay(dtRed);
            }

Did it work as expected? If not, no worries! Check your code using the troubleshooting steps from Lesson 3.
