Yet Another DTMF Controlled Robot



We have got a recent submission of the project by students of Mai Bhago polytechnic college, Amritsar, Punjab. As simple as it sounds, This project is an 8051 based DTMF controlled robot. 8051 receives decoded DTMF tones from MT8870 DTMF decoder. The DTMF input is fed from a GSM phone. There are two motors on the robot which are controlled via dual H-Bridge motor driver L293D.

If you are just starting to learn microcontrollers then this is the project you should start with. It will help you understand the basic IO control in microcontrollers using embedded C.

DTMF controls are as follows:

On pressing '2' robot moved forward
On pressing '8' robot moved backward
On pressing '4' robot moved left
On pressing '6' robot moved right
On pressing '5' robot moved stop


The download package includes source code, hex file, schematics and a description document.
