Exploring Variants: Atmega32 & ATmega8 in the Realm of AVR Microcontrollers

ATmega32 – 8 Bit AVR Microcontroller AVR microcontrollers operate on an advanced RISC architecture. ATmega32, a low power CMOS 8-bit microcontroller, is constructed upon the AVR enhanced RISC architecture. When the cycle frequency reaches 1MHz, the AVR is capable of executing 1 million instructions per second. Key Features: 32 x 8 registers for general working […]

Clock-Free Arduino: Maximizing ATmega328 Performance

Clock Projects / Ibrar Ayyub

While most opt for a 16MHz oscillator in a DIY Arduino setup, it’s intriguing to discover that the ATmega328 can function without it. An Arduino typically comprises various elements such as a linear regulator, USB to Serial microcontroller, debug LED, power LED, reset button, RX & TX LED, crystal oscillator, among others. However, a minimal

What is a Voltage Controlled Oscillator?

Blog / Muhammad Bilal

Introduction of Voltage Controlled Oscillator An oscillator is a circuit that generates a continuous, repetitive, alternating waveform in the absence of any input. Oscillators, in essence, convert unidirectional current flow from a DC source into an alternating waveform of the desired frequency, as determined by its circuit components. A voltage controlled oscillator (VCO) is

Interfacing DC Motor with AVR Microcontroller Atmega16

Motor Projects / Muhammad Bilal

DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about

How Oscillators Work

How It Works / Ibrar Ayyub

Oscillation Basics One of the most commonly used oscillators is the pendulum of a clock. If you push on a pendulum to start it swinging, it will oscillate at some frequency — it will swing back and forth a certain number of times per second. The length of the pendulum is the main thing that

How a Theremin Works

How It Works / Ibrar Ayyub

How it Works: The Science Behind the Magic Way back in the early 1920s, when Léon Theremin worked at the Physico-Technical Institute in St. Petersburg, Russia, he noticed that when he moved his body in or out of an electromagnetic field produced by a radio frequency oscillating circuit, he changed its frequency [source: Harrison]. The

1750 Meter Lowfer Band amplitude modulated RF source using ATtiny2313 microcontroller

Metering - Instrument Projects / Ibrar Ayyub

This is a low power signal source I put together one evening to provide 187 KHz RF signals for an anticipated receiver investigation. Under Federal Communications Commission rules inside the United States, one is allowed to operate a transmitter without a license under certain conditions. Here, I have copied the relevant section of the most

100 MHz RF oscillator using ATtiny12 microcontroller

AVR ATmega Projects / Ibrar Ayyub

I needed a frequency reference for tuning up the RS-232 to 100 MHz RF desktop channel adapter elsewhere on this site, when I found this Saronix crystal oscillator in my junk box. A few minutes with AVRStudio produced an ATtiny12 to make a tone – even fewer parts than using an NE-555. With the addition
