This project is a combination of the "Hello World!" project on the Arduino website (https://www.arduino.cc/en/Tutorial/HelloWorld) and the "Keyboard and Mouse Control" project on the Arduino website (https://www.arduino.cc/en/Tutorial/KeyboardAndMouseControl). It creates an LCD screen that displays the word "No" until the pushbutton is pressed, which then causes the LCD screen to display the word "Yes."

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather Materials
- 1 Arduino or Genuino Board
- 2 breadboards
- 1 10k Ohm resistor
- 1 1k Ohm resistor
- 1 potentiometer
- 1 LCD screen
- 20 hook-up wires
- 1 USB cable
Step 2: Build the Contruction
Build the construction according to the diagram from Step 1 and the schematic above. Notice where each resistor is placed, as they have different resistances.
Step 3: Write the Code
Write out the code on the Arduino software. The comments in brown explain what each line of code is doing.
Step 4: Test It Out
Connect the Arduino to the computer with the code on it using a USB cable. Verify and upload the code. The LCD should display the word "Yes" when the pushbutton is pressed and "No" when it is not pressed.
