Hi everyone,
As there are lots of websites which guide you teach you regarding the micro controller programming, though i am putting a little effort to make you guys understand the concept of micro controller programming, especially AVR ATmega16/8. Here we go through (we can say , GROW through) step by step learning.
this would be our step by step flow:
01)  What is a micro controller?
02)  What is special in AVR?
03)  GPIO programming of AVR.
      1)TEST  LED blinking
      2)LED Fadding
      3)Switch interface
04) UART Interfacing Example
05)  LCD Interfacing with AVR
     1) 8 bit mode
     2) 4 bit mode
06) Seven segment Interfacing
     1)Simple interfacing
     2)Multiplexing mode
07) DC motor interfacing
08) ADC programming
09) Timer interrupt
10) SPI interfacing example
11) I2C/TWI Interfacing Example
