This project shows how a basic interrupt works on the Arduino. It displays a message and then another one when the interrupt occurs.

Step 1: Step 1: Add Push Button to Breadboard

1. Attach pushbutton to the middle of breadboard as shown.

2.Place 10K resistor to left side of pushbutton and connect to ground rail

3. Place a jumper wire to left side of pushbutton and connect to power rail

4. Place a jumper wire on the same side as the resistor and connect the other end to pin 2.

Step 2: Step 2: Attach an LCD Screen and Potentiometer

Connect the LCD directly to the breadboard and connect a wire jumper to each pin as pictured.

The order goes.
Ground

Power

Pin 13

Pin 12

Pin 11

Pin 10

Empty

Pin 9

Ground

Pin 8

Potentiometer (Connect to power and ground)

Note that there are 4 empty pins that we do not need to connect in the middle.
