Arduino Stopwatch

I have created a stopwatch using push buttons and a potentiometer to control the LCD screen display. It counts in seconds and allows for you to start and stop at your choice.

Supplies

Wires

Potentiometer

Push Buttons

Arduino Uno

10K Resistor

LCD Display

Step 1: Create Baseline for Breadboard

Apply LCD to Breadboard and attach wiring from LCD to Arduino

If needed help to add wires, use SIK Guide booklet

Step 2: Push Button and Resistor

Add Push Buttons for usage of stopwatch and add 10K resistor inline of Push Button

Also add Wire inline of resistor to generate power

Step 3: Add Code

Once wiring and all has been built, add appropriate code to Arduino IDE

Step 4: Usage

LCD should turn on and can be monitored through Potentiometer

This can change the brightness of the LCD display to your liking
