Those how are building microcontroller based project for little long must have got bored with the good old character LCDs. Whether you are bored or your application require to present more data to the user in a better way, you need Graphic LCD. Character LCD Interfacing is [...]

Hello All, Sometimes the Internal ADC is not enough. Like when you need more resolution or high speed. The internal ADC of AVR generally has the following specifications. 15K samples per second 10 bit resolution. If you need more than that you need an external ADC. You may also need external [...]

Real Time Clocks, as the name suggests are clock modules. They are available as integrated circuits (ICs) and manages timing like a clock. Some RTC ICs also manages date like a calendar. The main advantage is that they have a system of battery backup which keeps the clock/ca lender [...]

In this turorial we will see how we can easily interface a 24C series serial EEPROM with AVR microcontrollers. What is an EEPROM? An EEPROM is kinds of novalatile memory, that means it is used for storing digital data permanently without any power suply. EEPROM stands for Electrically Erasable Programmable Read [...]

Till now we have seen the basics of RS232 communication, the function of level converter and the internal USART of AVR micro. After understanding the USART of AVR we have also written a easy to use function to initialize the USART. That was the first step to use RS232. [...]

Merry Christmas !!!

Hello Friends, Welcome back. In previous tutorial I introduced my IR remote decoding library. In this tutorial I will continue our discussion and show you how to add IR remote controls support to your AVR projects. Step I Download the library files and unzip them in a folder. Step II In AVR [...]

Hi Friends, Welcome to my AVR tutorial Series. In this article I will describe my Infrared Remote Control Library. Hope you will enjoy it. I was very much amazed my remote controls since long. The simple circuits described in magazine were just operated like a switch and can only switch on and off [...]
