// Set the strength of the motor's buzz to three different levels void setup(){ pinMode(3,OUTPUT);//Set pin 3 to receive power } void loop(){ analogWrite(3,80); //Set motor strength to 80. It can range from 0-255 delay(1000); //Wait 1000 milliseconds (1 second) at strength 80 analogWrite(3,160); //Set strength to 160, double the last function delay(1000); //Wait 1000 milliseconds analogWrite(3,240); //Set strength almost to maximum delay(1000); //Wait 1000 milliseconds before restarting the loop } // (c) 2023 Let's Start Coding.

Challenges

Can you complete the challenge? Change the code in your code editor above. Upload your code to see the effect when you're finished. Complete a challenge? Check it off the list!

Change the speed of the delays inside the void loop function so the motor speed rises twice as fast.

Add more analogWrite( ) functions and delay functions to make the motor rise more smoothly and gradually.

Change the second argument in the analogWrite functions so the motor isn't "revving up", but instead its power is jumping all over the place. The more analogWrite functions you have, the more random this will seem!
