Serial communication (Data receive) using AVR Microcontroller (ATmega16) USART

Leave a Comment / Using Atmega /

Communication between two entities is important for the information flow to take place. In general the information transport system can be parallel in which the complete byte of data is sent at a time, with each bit having a separate dedicated line or it can be serial where only one communication line is available which

How to use inbuilt ADC of AVR microcontroller (ATmega16)

Leave a Comment / Using Atmega /

Microcontroller understands only digital language. However, the inputs available from the environment to the microcontroller are mostly analog in nature, i.e., they vary continuously with time. In order to understand the inputs by the digital processor, a device called Analog to Digital Converter (ADC) is used. As the name suggests this peripheral gathers the analog information
