Web based AVR Project

          This AVR Project is derived from the idea to control home appliances through web. It is a combination of web application and avr circuit. This project consist  python(flask frame work ) as server and JavaScript with HTML5 as client. The User Interface and avr microcontroller is communicate through serial port of PC.

CIRCUIT DIAGRAM

Circuit is divided into two parts, microcontroller-circuit and serial port interface.
The main circuit consist of atmega8 microcontroller, four leds connected to PORTD (pins-6,11,12,13) and a potentiometer in pin-23(ADC0).The MAX232 used as level converter for communicating the USART of atmega8 with serial port(PC).USART is simply a form of serial data communication.

main circuit

Microcontroller and PC communication using RS232: RS232 is the encoded version of USART.
