Interfacing Servo Motor with Atmega32 Microcontroller
Servo Motor Servo Motor is a DC Motor equipped with error sensing negative feedback to control the exact angular position of the shaft. Unlike DC Motors it will not rotate continuously. It is used to make angular rotations such as 0-90°, 0-180° etc. Stepper Motors can also be used for making precise angular rotations. But Servo Motors are preferred in angular motion applications like robotic arm, since controlling of servo motors are simple, needs no extra drivers like stepper motor...
Interfacing DC Motor with Atmega32 Microcontroller
In some of your electronic projects you may want to control a DC Motor with Atmega32 Microcontroller. We can't connect a DC Motor directly to a microcontroller due to following reasons. A microcontroller can't supply the current required for the working of DC Motor. ATmega32 Microcontroller can source or sink currents up to 40mA but a DC Motor needs current very much more than that. The negative voltages created due to the back emf of the motor may affect the proper functioning of the microcontroller. You may need to...
Interfacing LCD with Atmega32 Microcontroller using Atmel Studio
As we all know LCD (Liquid Crystal Display) is an electronic display which is commonly used nowadays in applications such as calculators, laptops, tablets, mobile phones etc. 16x2 character LCD module is a very basic module which is commonly used by electronic hobbyists and is used in many electronic devices and project. It can display 2 lines of 16 character and each character is displayed using 5x7 or 5x10 pixel matrix. 16x2 Character LCD Interfacing 16x2 LCD with Atmega32 Atmel AVR Microcontroller using...
Using Push Button Switch with Atmega32 and Atmel Studio
Push Button Switch This tutorial is meant for beginners in the field of Atmel AVR programming. I hope that you already read my first tutorial Blinking LED using Atmega32 and Atmel Studio. In most of the embedded electronic projects you may want to use a push button switch to give user inputs to the microcontroller. To use a push button switch with a microcontroller, first you should configure the corresponding...
Blinking LED using Atmega32 Microcontroller and Atmel Studio
Similar to printing 'Hello World' in C or C++, the very first step towards programming a microcontroller is Blinking a LED with a delay. Atmega32 is a very popular high performance 8 bit AVR Microcontroller. For this example project we need to use two registers DDR and PORT. DDR stands for Data Direction Register, it determines the direction (Input/Output) of each pins on the microcontroller. HIGH at DDR register makes corresponding pin Output while LOW at DDR register makes corresponding...
