In this tutorial, we will see how we use timers on AVR microcontrollers. A Timer is actually a counter that counts every time the microcontroller executes an instruction. There are one to six timers in AVR microcontrollers, depending on their family architecture. The AVR timers are 8 bits and 16 bits. The 8-bit timers are … Read more
This article will teach you how to interface a microcontroller with an optocoupler. How can you interface AVR, PIC, and 8051 microcontrollers with an optocoupler? What exactly is an optocoupler? What are the fundamental principles of an optocoupler? Power electronics projects, such as firing angle control circuits and AC power control circuits, often rely on … Read more
In this tutorial, we will discuss the LCD display and its interfacing with the ATmega32 AVR microcontroller. We will use the 8-bit mode to transfer data to the Display. We will also look at the basic difference between 8-bit mode and 4-bit mode. How do we write code for LCD interfacing in C, and what … Read more
In this tutorial, we will learn about the push button and how to use it with the AVR ATmega32 microcontroller. We can use this button to control any device, but we will use an LED for this example. Here we will also learn the use of “if and else” statements in C. If this is … Read more
In this tutorial, we are going to look at how to blink an LED using the ATmega32 AVR microcontroller. This article will discuss the basics of programming an AVR ATmega32. We will learn how to develop codes for blinking LEDs using the ATmega32. You will also learn how to determine the direction of I/O pins and … Read more
