Starting from remotely switching on/off a LED light and reading sensor data feedback from an Arduino microcontroller board, the app can do so much more such as controlling 4 analog outputs or 4 servo motors or 2 out of each outputs in the same time. Three functions can be executed separately with the help of 2 auxiliary buttons.

There are 4 projects resources (3D model, coding and schematics) shared in the app. The 4 projects are
(1) Sleeping Lamp
(2) RGB Ring powered Geode City
(3) Robot Fan
(4) Robot Arm
