New Guide: RGB Matrix Money-Sensing Tip Jar with an RGB Matrix
Check out the latest tutorial from Erin St. Blaine: make a money-sensing tip jar that shows your gratitude whenever someone leaves you a tip. A sensor inside the jar’s lid triggers a “thank you” animation when someone drops a coin or a bill through the slot. This project seems great for coffee shops, pass-the-hat gigs, and most especially for night time buskers since your message will shine bright where everyone can see.
From the guide:
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.
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 pre-made images or upload your own animations to make a custom “thank you” message for your most generous customers.
