Bluetooth operated switchyard(model)

This project is a small model layout of switchyard. I used electromagnetic relays in the place of isolators and circuit breakers. The model is done for a 2 incoming and 4 outgoing Lines along with a tie line unit. This units are controlled using android software with Bluetooth interface.
ATmega8 is used as core controller
HC-05 bluetooth device is used.
12 electromagnetic relays is used as electronic switch.

UART interfacing of ATmega8

Demo project. Teaching my friend about microcontroller.. :-)

Web controlled electrical devices using IOT(Internet Of Things)

Internet of things is a booming technology in Embedded systems.
This project uses a web site hoisted in a server (www.myiotproject.com) to control th home appliance.
The unit contains an ATMEGA8(AVR) microcontroller witch act as a processor for the entire system.
