How to control DC motor speed using PWM on Atmega32

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 …

Programming ATtiny85 with Arduino Uno

Leave a Comment / PWM Projects / By Ibrar Ayyub

Story I am working on a project which requires reading multiple sensor data on different locations. These require only few PWM pins so using multiple Arduino Uno would be expensive and unnecessary. So I decided to use ATtiny85 microcontroller in place of Arduino Uno development boards.ATtiny85 is a cheap and powerful alternate when u don’t …

Markov Music Box

Leave a Comment / PWM Projects, Sound - Audio Projects / By Ibrar Ayyub

markov summary Traditional music boxes play one or two tunes very well, but are not very interactive. Put differently, they have a high quality of synthesis, but a fixed-pattern note sequencer and fixed tonal quality. I wanted to build a device which would play an interesting music-like note sequence, which constantly changed and evolved, with …

Introduction to AVR Microcontroller Pulse Width Modulation (PWM)

Leave a Comment / PWM Projects / By Ibrar Ayyub

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 …

AVR Twinkle Twinkle Using PWM Project

Leave a Comment / PWM Projects / By Ibrar Ayyub

Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style. The principal …

AVR LCD Thermometer Using ADC and PWM Project

Leave a Comment / PWM Projects / By Ibrar Ayyub

Sometimes we need our microcontroller to interact with more human readable information. It will be better for us if we could make it display the words not just blinking the LED. Today most modern gadget such as mobile phone and PDA, use LCD (Liquid Crystal Display) for interacting with us. In this project we will …

Controlling DC motor with AVR ATtiny13 PWM and ADC Project

Leave a Comment / PWM Projects / By Ibrar Ayyub

It’s interesting to explore what we can do with this tiny 8 pins; 8-bit microcontroller. The ATtiny13 is the smallest and cheapest Atmel AVR 8-bit microcontroller families but yet, it’s loaded with sophisticated peripherals such as two 8-bit PWM channels and 4 channels 10-bit ADC. Although the memory is quite small; 1 K flash, 64 …

PWM Motor Driver with MOSFET H-Bridge and AVR ATmega8

Leave a Comment / Motor Projects, PWM Projects / By Ibrar Ayyub

Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge. Here, direction is controlled using a two-position toggle switch and speed of the …

Working with Atmel AVR Microcontroller Basic Pulse Width Modulation (PWM) Peripheral

Leave a Comment / PWM Projects / By Ibrar Ayyub

Pulse Width Modulation (PWM) is a technique widely used in modern switching circuit to control the amount of power given to the electrical device. This method simply switches ON and OFF the power supplied to the electrical device rapidly. The average amount of energy received by the electrical device is corresponding to the ON and …
