A very good wireless local area network (and personal) is undoubtedly the Bluetooth (BT). Today in our day-to-day is common to find us with cell phones, stereos, cameras, etc., interconnected with the help of the famous "blue little light”.
In the world of IoT and automation in general, it is very common find remote controls via mobile phones using BT technology. This is due to two basic components, but very important:
- Simple Development Platforms for ANDROID apps (like MIT AppInventor2) Cheap and
- affordable BT modules (eg HC-06)
In this instructable, I will develop some ideas about controlling Arduino’s outputs through a mobile device in order to move a Robot, turn on lamps on a house, etc.
