# Matrix Portal Money-Sensing Tip Jar

## Overview

https://youtu.be/l6O_qA9G6qs

Say "Thank You" in a fun and interactive way with this money-sensing tip jar. Whenever someone drops in a tip, the LED matrix at the back of the jar will reward them with a fun animation and some heartfelt gratitude.&nbsp;

This is a fairly easy build, using an upcycled snack jar to collect your bountiful tips and powered by a Matrix Portal M4 board plugged into the RGB matrix of your choice. Use our premade images or upload your own animations to make a custom "thank you" message for your most generous customers.&nbsp;

# Difficulty Level

This is a beginner project that doesn't require any soldering - you just need a screwdriver, some cutting tools, and some strong tape. I've also included an option that uses soldered headers for a slightly more secure build.

# Materials Needed
A plastic jar with a lid, large enough to hold ALL the tips.

Choose the RGB Matrix size that best fits your jar. [You can see all the different sizes here](https://www.adafruit.com/category/327). I used the 4mm pitch 64x32 size.

You'll also need a Time of Flight sensor. This is a very cool little sensor that uses a laser to detect proximity, and works within a really tiny range of a few millimeters.

Be sure to get one of the suggested cables to attach it to your Matrix Portal as well. Check out the "Add the Sensor" page for more details.
