//Use a rising variable for the strength of the motor. int strength = 0; //Create an integer variable called 'strength' void setup() { pinMode(3,OUTPUT); //Motor } void loop() { analogWrite(3,strength); //set the strength of the motor equal to the variable strength++; //Increase the variable value by 1 delay(50); // delay 0.05 seconds before the loop starts again. if(strength>255){ //when strength increases beyond analogWrite's max value of 255 strength=0; //reset the variable to 0 } } // (c) 2023 Let's Start Coding.

Challenges

Can you complete the challenges? 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!

Update the 'if' statement so the motor resets when it is at half strength.

Add an LED light and use the strength variable to decide how bright it is. Is there a better variable name that would apply to both the motor and the LED?
