Introduction Atmel, AVR microcontrollers (MCUs) are very easy to use. All AVR microcontrollers require Integrated Development Environment(IDE) such as Atmel Studio. Using this IDE, we can create, compile, and debug programs on all AVR microcontrollers. Atmel Studio is available free of charge. To download and install the latest Atmel studio use this link. Note: There are possibly …
One of the interesting projects for most of the embedded beginners enthusiasts or hobbyists is to build the LED chasing effect. In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment …

In this project we built a sketchpad based on LED matrix display with microcontroller and resistive touch screen control. We used a single point resistive touch screen to detect the user’s gesture and microcontroller’s analog/digital converter (ADC) ports collects the data and convert it to coordinates. We designed a LED drive circuit with shift registers …
ukule-LED is a ukulele with LEDs embedded in its fretboard. These LEDs can light up in configurations corresponding to different chords, which can aid the ukulele player in learning how to play certain chords, or can act as a chord reference for a more advanced player. ukule-LED has two modes of operations. First, in “play” …
Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32 …
I fully designed from scratch every single piece of this project to create a cool glowing Magic LED Cube, mainly made for light animation and basically could be explored for decoration of Electronics Labs. Designed around the awesome RP2040 Microcontroller and Built with a full of electronics passion All the used items are fully documented through this post …
Welcome to my version of the LED reactive table! I was inspired by previous work using discrete LEDs, such as this one, but I figured it would be easier and more fun to use NeoPixels — programmable RGB LEDs that can be set to any color you want. The table consists of a large array of infrared emitters …
The Classic ATtin85-20PU is a very simple project that is also very fun to make. It really is perfect for a parent/child combo because it’s quick! Builds in minutes. But it does teach several electronic hobbyist skills.There is a story behind my decision to become infatuated with signal lights. My friend invited me to his …
An interesting project and already much discussed in the forums and also in videos.Although it appears complex,it is a simple idea and fun very purpose. Mounting material: – 27 LEDs matte– Microprocessor ATmega8– Electrolytic capacitor 47UF 16V– Veroboard– Small wood board at the minimum 10x10cm– 50 cm wire tinned (excuse me, I’m portuguese and my …
This example code and simple wiring demonstrated how to setup an AVR ATtiny85 processor to react to external interrupts. Whenever the voltage changes on the chosen input pin (pin 6 / PB1), it executes the interrupt service routine (ISR), checks the current voltage, and sets the output pin (pin 3 / PB4) to match. This …
