Transforming your AVR Microcontroller to the I2C or TWI Slave I/O Expander Project

The I2C bus (read as I squared C) is one of the most important embedded system serial bus interface first introduced by Philips in 1980; using just two lines called SCL (serial clock) and SDA (serial data) respectively make the I2C bus is a perfect choice to provide additional I/O capabilities to your microcontroller project […]

How to use I2C-bus on the Atmel AVR Microcontroller

I2C (read as I Squared C) bus first introduced by Philips in 1980, because of its simplicity and flexibility the I2C bus has become one of the most important microcontroller bus system used for interfacing various IC-devices with the microcontroller. The I2C bus use only 2 bidirectional data lines for communicating with the microcontroller and

Using Serial Peripheral Interface (SPI) Master and Slave with Atmel AVR Microcontroller

Sometimes we need to extend or add more I/O ports to our microcontroller based project. Because usually we only have a limited I/O port left than the logical choice is to use the serial data transfer method; which usually only requires from one up to four ports for doing the data transfer. Currently there are

Working with AVR microcontroller Communication Port Project

Back in the old days the COM port or known as RS-232 (EIA-232 standard) is one of the essential communications protocol and hardware use in many computer system installation start from small UNIX machine to the mainframe. The RS-232 protocol is used by terminal such as wyse60 or DEC vt100 which connected through direct cable

An advanced energy saver project with DTMF capabilities to use electricity efficiently by reducing the unwanted uses.

INTRODUCTION:   A lot of electricity is wasted due to ignorance or fault of the user. Sometimes a person in the room turns on all the electric equipments which is of no use to them. As an example, supposedly a person enters in the hall or conference hall (where a large number of tube lights or fans
