Pete’s Valentine’s Day Box Project

I decided that for our son’s kindergarten Valentine’s day box I would implement a sensor and some programmable LEDs and an 8×8 LED Matrix with an Arduino Microcontroller to make his mailbox the most festive ever.

We used the following components:
1 – 1 Meter Strip of Self Adhesive Neopixels

1 – Arduino Uno

1 – IR Line Following Module

1 – 8×8 LED Matrix with a Maxim Driver IC
(https://www.amazon.com)
1 – Piezo Buzzer
(https://www.adafruit.com/products/160)

Below is the initial sketch / block diagram of the system:

I also made a quick video and posted it to YouTube to review the project and how it works:

All of the code that I used to implement this is hosted on GitHub here:
