AVR_ATmega16

Here, you will find interfacing of various kind of sensors with ATmega16. I am using Microchip Studio for programming and Proteus software for simulating the circuits.

About

Here, you will find interfacing of various kind of sensors with ATmega16. I am using Microchip Studio for programming and Proteus software for simulating the circuits.
