RS232 is a asynchronous serial communication protocol widely used in computers and digital systems. It is called asynchronous because there is no separate synchronizing clock signal as there are in other serial protocols like SPI and ...

Hi Friends, Wish you and your whole family and friends a very very happy Diwali !!!

Hello and welcome back to the discussion on the TIMERs in compare mode. In the last article we discussed the basics and the theory about using the timer in compare mode. Now its time ...

Hi Friends, In last tutorials we discussed about the basics of TIMERs of AVR. In this tutorial we will go a step further and use the timer in compare mode . In our first tutorial on timer ...

By interfacing different types of sensors with our MCU we can sense the environment and take decisions, in this way we can create "smart" applications. There are wide variety of sensors available. In this tutorial we ...

Hi Friends, In last tutorial we discussed about Multiplexing Seven Segment Displays. So you must be very much familier with the therory. Now let us write the code and design a small project that will make you expert in using these ...

We have discussed the basics of seven segment displays on our tutorial “Using Seven Segment Displays with AVR MCUs”. So you should be familiar with them. In this tutorial we will discuss about multiplexing of seven segment displays.Multiplexing is required ...

Timers are standard features of almost every microcontroller. So it is very important to learn their use. Since an AVR microcontroller has very powerful and multifunctional timers, the topic of timer is somewhat “vast”. Moreover there are many different timers ...

Most of the physical quantities around us are continuous. By continuous we mean that the quantity can take any value between two extreme. For example the atmospheric temperature can take any value (within certain range). If an electrical quantity is ...

Each AVR MCU has several internal peripherals that give powerful abilities to your projects. For example internal ADC can be used to convert analog value (say voltage output of some sensor) to a digital value that you can use. And ...

LCD Interfacing with AVR Microcontroller. When you start working with LCD modules you will start feeling the real power of MCU and your imaginations will be touching sky you will wonder how many exciting a powerful gadgets ...

Motor gives power to your MCU. Ya power to do physical works, for example move your robot. So it is essential to know how to control a DC motor effectively with a MCU. We can control a DC motor easily ...
