Digital Piggy Bank

About: 4D Makers is a group of curious engineers and enthusiasts who finds great satisfaction in creating and building anything from electronics.

The origin of piggy banks dated back nearly 600 years before real bank even exist. It is mostly made up of dishes and pots created out of economical orange-colored clay called pygg. Over the next few hundred years, as the English language evolved, the clay (pygg) and the animal (pigge) came to be pronounced the same that’s why it now commonly known as a piggy bank. But this version of piggy bank is incorporated with a new technology. It utilizes gen4 50” HMI display that allows the user to interact with the display as well as monitor the current savings. It also contains a coin counter designed to count 3 different coins updating the current savings.
