A Bluetooth receiver modem receives these commands and moves the antenna based on the input parameters provided.

There are precisely three input parameters:

  • The first parameter step determines the angle in which the antenna should move. 
  • The second parameter specifies whether the antenna should move in a clockwise or an anticlockwise direction. 
  • The third parameter determines the speed in which the antenna should move. The speed parameter includes L for low, M for medium, and H for high speed. 

20. Hovercraft

This project involves the creation of a hovercraft that can be controlled via an Android application. The Android app sends commands to the hovercraft circuit for moving the device. The circuit comprises a Bluetooth receiver that receives and processes the commands. The commands received by the Bluetooth receiver are further processed by the microcontroller, which dictates the final movement of the hovercraft. 

The hovercraft you will design will require high RPM motors interfaced with an AVR family microcontroller to achieve the desired functionality. There are three motors involved in the design of this hovercraft. The motor situated below the hovercraft rotates at a very high RPM, thereby imparting to it enough force so it can hover above the surface level.

The friction remains at a minimum. A motor propeller is mounted behind the hovercraft to allow it to move in the forward direction. The servo motor attached to the hovercraft rudder helps it to move in every direction by bending the air at accurate angles.
