Introduction
In this tutorial we will see about building a simple dtmf controlled robot. Whenever we make a call, and press keys, dtmf tones are generated and transmitted. The tones can be easily decoded using a IC like MT8870. This enables a lot of possibilities for wireless control over mobile and telephone.
The Components
For this we will be using Xplore Robot Chasis as shown. The basic components would be
- Xplore Robo Chasis
- Xplore AVR Robo development board with Integrated DTMF
- Battery Operated [BO] Motors for driving wheels
- Castor as a free wheel.
The setup is shown in the pictures below.
You could make your own hardware setup as per the schematics discussed in the tutorial.
