What voltage level do you need to power your display?

5V

What voltage level do you need to power the display backlight?

3.5V

What was one mistake you made when wiring up the display? How did you fix it?

It worked for me the first time. But, I struggled with using the rotatory encoder for my timer part. I wanted to use the button part of the rotator to work as a state changer. I was expecting the loop option will get the state of the button as pressed or released, but that didn't work. After pressing the button, I was continuously getting the HIGH value in the digitalRead. I used a switch button instead, which also had the same problem. After using a logic in the code to detect state switch, I was able to emulate the pressed/released option correctly in the code.

What line of code do you need to change to make it flash your name instead of "Hello World"?

lcd.print("Sunny Ladkani!");

Include a copy of your Lowly Multimeter code in your lab write-up.

Multimeter Code

How would you change the code to make the song play twice as fast?

int noteDuration = 1000 / noteDurations[thisNote]; to int noteDuration = 1000 / noteDurations[thisNote]/2;

What song is playing?

I think it's the star wars

Make a short video showing how your timer works, and what happens when time is up!

Timer Video

The timer works as a state machine.

• To start, you press the button at the centre of the breadboard.
• You are taken to the "main menu" state where you can select the following -
  • Set Timer
  • Clear Timer
  • Go Back
• When you press the button for "Set Timer", you are taken to a new state where you can use the rotatory encoder to input time. * On next press, you are given the option to start timer or go back.
• On press, the timer starts and when it finishes, the "Star wars" music plays.
