Motivated and detail-oriented Electronics and Communication Engineering student seeking to leverage technical knowledge, analytical problem-solving skills, and a strong aptitude for learning to contribute to organizational success in a challenging engineering role.
This project implements a Dual Tone Multi-Frequency (DTMF) based load control system using an Arduino Uno and an MT8870 DTMF decoder. It allows users to remotely switch electrical loads such as bulbs or fans ON and OFF by pressing keys on a mobile phone during a call. The DTMF decoder detects the keypad tones, and the Arduino processes these signals to control a relay module connected to the electrical loads. This system demonstrates a simple, reliable, and cost-effective method for remote home appliance control.
