Blink Delay Divides By Two

Code

The code in the editor below is ready to run! Plug your Code Lab in to your computer's USB port with the cable and hit 'Upload Your Code!' to see what it does. Change something in the code, like a delay or pin number. Try to add something new to the program - it's yours to tinker with! You can always press the 'Restore' button to return the code to the working example.


/* Blink an LED with a delay variable that gets cut in half every loop */ int wait = 5000; //Create a variable called 'wait' that is an integer (whole number) and has a starting value of 5000. void setup(){ pinMode(2,OUTPUT); //LED light } void loop(){ digitalWrite(2,HIGH); //turn on the LED light delay(wait); //delay for the number of milliseconds equal to 'wait' variable. First loop=5000, second loop=2500, and so on digitalWrite(2,LOW); //turn off the LED delay(wait); //delay for 'wait' number of milliseconds wait = wait/2; // divide 'wait' variable by 2. The single = sign means you're assigning the variable a new value. } // (c) 2021 Let's Start Coding. License: www.letsstartcoding.com/bsdlicense
