In many applications, it is important to control the speed of DC motor where precision and protection are essence. Here we will use a technique called PWM (pulse width modulation) to control the speed of DC motor. We can achieve speed control of DC motor using mechanical or electrical techniques but they require large size …
PWM Based DC Motor Speed Control using Microcontroller Using Atmega Read More »
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 …
Introduction to AVR Microcontroller Pulse Width Modulation (PWM) Using Atmega Read More »
Using PWM (Pulse Width Modulation) to control a device is a common practice in embedded systems; for example, you can use it to control the light intensity of a LED or control the speed of a DC motor. In this article, we will explain how to get a PWM from the AVR Atmega32 and we shalll …

Summary We used two stepper motors to drive a steel ball scavenged from a ball-bearing. These motors were controlled by a PS/2 mouse wirelessly using the RCR-433 and RCT-433 receiver/transmission combination mentioned in lecture. We then took the PS/2 protocol, made it compact, modified existing transmission code and deduced a way to control the robot …

Line follower is an autonomous robot which can detect a specific colored line painted on a surface of different contrast, such as white on black. In this project I used infrared transmitters and receivers to track the black strip on white surface. Due to the difference of infrared reflection on black and white surfaces, it …

Description With this circuit you can drive a unipolar stepper motor. It operates in full step mode. You can get a stepper motor from an old 5.25 disk drive. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the output for the driver …
