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

Usage
LCD should turn on and can be monitored through Potentiometer
This can change the brightness of the LCD display to your liking
