ATmega32 Switch Toggle Program

ATMega32 switch code is extremely simple to implement, and this article looks into how to write the code to make an LED light up when a switch is pressed. The atmega32-switch-code.c program tests the switch input to the ATMega32 Development System. There are many ways to write the code, but I have chosen the simplest way possible so everyone can understand. Therefore, instead of using “case”, I am using “if ...

ATmega32 blinking LED Lights

Using the ATMega32 microcontroller to flash or blink some LEDs is extremely simple and this tutorial shows how to make a blinker circuit including the example program code to blink eight LEDs. In this tutorial, you will learn how to make a program to blink eight LEDs sequentially, how to generate the hex file in AVR Studio, and how to transfer it into the ATMega32 memory using PonyProg2000. This is a multi- ...

Introduction to AVR Microcontroller Pulse Width Modulation (PWM)

PWM is used in many industrial mostly for controlling the motor speed. The PWM is used because it’s the most efficient method comparing to the analog one. That’s why most of the modern microcontrollers today have this features build in. How does this PWM works will be described on the following circuits: On the figure 1A the motor is controlled by applying continues current through transistor base lead and ...

The LED Chasing Effect Project using Atmel AVR Microcontroller

One of the interesting projects for most of the embedded beginners enthusiasts or hobbyists is to build the LED chasing effect. In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment (IDE) to program the project. The LED Chasing Project To complete the pro ...

Analog to Digital Converter of ATmega32 with LED Display

Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades of gray. What if the signal is 2.72V? Is that a zero or a one? We often need to measure signals that vary ...
