This tutorial introduces programming for AVR microcontrollers. It uses the ATmega328p found on Arduino boards, but works with straight AVR C and a bare microcontroller. It covers the basic information you need to get started, whether or not you’ve used Arduino or other microcontrollers previously. Why would you want to learn AVR programming (instead of, […]

New „hardwired“ TCP/IP chip from company Wiznet resists attacks, it´s fast and consumes only a minimum energy and host MCU resources. TCP/IP solutions from company Wiznet are known by its resistance resulting already from their principle . all the solution is hardware-based, thus it´s not possible to change a basic functionality of a device (flooding, […]

More than a year ago, a friend of mine asked me to write the software for his 3D Spectrum Analyser (3DSA): a device that takes as input an audio signal, and outputs its visualisation on a 3D matrix of leds. If the above description doesn’t quite ring a bell, simply watch the end result in […]

High power of the UDOO “asks” for usage. One of many occasions to make it is to use various available periphery thus gaining a truly universal platform. Favorite powerful embedded SBC called UDOO (S975-G000-2100-C2) already found many fans. Maybe also because of its compatibility with the Arduino Due platform (hardware and software) and mainly, it´s […]

If you’ve ever wanted to power your Arduino or AVR from a battery for development testing (batteries have different power delivery qualities than, say, transformed AC or even a regulated wall wart in DC) testing but were tired of going through batteries (Hey, I admit I’ve sucked batteries dry in hours because of a slipped-up […]

The Yún is unique in the Arduino lineup, as it has a lightweight Linux distribution to complement the traditional microcontroller interface. It also has WiFi and Ethernet connections on board, enabling it to communicate with networks out of the box. The Yún’s Linux and Arduino processors communicate through the Bridge library, allowing Arduino sketches to […]

As electronic products get smaller and better, so must the converters powering them. Besides delivering higher efficiency from a smaller footprint, these DC/DC converters must also respond rapidly to varying loads while making the system designers’ jobs simpler. Consequently, power supply makers continue to tap the benefits of advances in packaging, architecture, and semiconductor processes […]

Summary: The following is a step by step guide on how to make a Heat-Seeking Desk Fan from an Arduino microcontroller, a computer fan, a servo, and an infrared temperature sensor. The device scans the room periodically, automatically pointing itself in the hottest direction (ideally towards a person). This is a working proof-of-concept model, but it […]

Before I start I guess I must answer 2 questions which would be asked inevitably: 1) Why? Because I can. To learn how electronics behave at cryogenic temperatures. And just curios how much juice you can squeeze out of AVR if you push hard enough This also produced some results relevant to desktop processors overclocking […]

One day I was sitting behind my desk at work and I got that weird need to build something, after looking around for a bit I got my eye on an LED matrix and that sparked an idea in my head : “I WANNA MAKE A TAMAGOTCHI”. So for those of you that don’t know […]
