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

Controlling DC motor with AVR ATtiny13 PWM and ADC Project

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

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

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
