“Hi in this instruct I will show how to build a small game used for practice mathematics, with an Arduino Uno and an Oled display.
It all started when I was helping my son with his schoolwork.
I came up with the Idea to make a device use to practice the analog clock and the basic arithmetics.
If you have read my other instruct, “OLEDDICE you probably recognize the box and other things from that project.
When I did the design for the dice project I bought several custom-made PCB s and designed them for a specific box, therefore I will reuse it for many portable projects.
Because of the above the video showing the final custom brain-game and how to use it, but in this instruct I will describe how to build it on a breadboard.
There are two version available.
1. Standard version
2. AutoPowerOff Version
The AutoPowerOff version has a few extra components added to switch off the power automatically to save batteries.
It is the perfect choice if you, like me make one to be portable.”
