Tri Wheel

The Tri Wheel is a STEM PBL interactive eBook of handheld touch screen-controlled (a minicomputer) technology that utilizes Bluetooth communication. It is driven by its 2 rear wheels driven separately, that is supported by a front ball wheel. It uses an Arduino Uno Rev3 as the main microcontroller board on its circuit assembly and communicates with a self-made minicomputer used as the handheld computer.
