1. Mobile Controlled Robot
This project involves building a robot that can be controlled by sending the instructions to the mobile phone that is connected with it. The robot functions using the DTMF (dual tone multiple frequency) technology to establish the connection. The application of this robot varies from remote monitoring to surveillance.
2. Home automation using DTMF Decoder
In this era of technological advancement, we use automation for everything. There are many techniques to control devices automatically using Arduino, raspberry pi, which requires internet and some more modules to make it work.
It also requires a lot of programming to be done to make it work. Besides, this technique is costlier as we are using sensor and many more things, to control the respective appliances.
