GUI Frameworks of all modern OS like Windows, Linux (Qt & GTK+), MAC etc have a concept of standard dialogs. For example all applications running under Windows shows the same file open dialog for selecting a file. Similarly their are ...

In the last tutorial, I explained you how to use our SoftI2C library to read and write a 24CXX series I2C EEPROM. Now I will continue our exploration and write a register access layer for the DS1307 chip. The DS1307 ...

In this tutorial I will show you how to use our easy to use open source Soft I2C library to access a 24C64 EEPROM chip. We discussed the library in our previous tutorial. The functions developed in this tutorial will ...

Today I am going to explain a helpful technique used while designing embedded system. The technique is to expand the number of input and output lines available in any microcontroller. The idea is to use a shift register, a shift ...

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 ...

Many project requires some kind of Audio output. For example a burglar alarm, an automated school bell or simple electronic games or even a robot! In Old days we used some some dedicated Music and Audio ...

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 ...

In this tutorial we will set up the TIMER0 in fast pwm mode and use it to generate PWM signals of varying duty cycles. In this way we would be generating analog signals of voltages between ...
