Like most one-year-olds, CodeParade’s son really likes pushing buttons. Rather than purchasing a so-called busy board that might teach him skills like unlocking doors or plugging in electrical outlets, he decided to build his own custom device controlled by an Arduino Uno.

The resulting toy features a wide variety of lights, buttons and switches, and makes sounds to keep the little guy entertained. In the center, a big green button activates an analog voltmeter, which not only looks cool, but actually indicates the battery level of the unit.

While you probably won’t want to build this exact interactive box, CodePanda’s project is available on GitHub for inspiration and/or modification!
