LOG: Made a correction/modification Step 3 and added a picture step 5. So many Arduino users have RBBBs(Really Bare Bones Board (Arduino))  or Anarduinos or Boarduinos that could use a USB interface to program and power them but don’t want to spend $15-20 for a USB BUB or FTDI cable. This Lazy Old Geek is […]

Have you ever wanted to use a good old knob to control your TV volume instead of repeated button pushing? Or make it controlled by light? Do you want your remote to be replaced by an awesome arduino and let it do the hard work of using a remote for you? Well this instructable is […]

Overview In this tutorial, you’ll learn how to control a DC motor’s direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and brands of […]

Introduction This design project utilizes an Arduino MEGA2560 with an ATMEGA1280-16AU microcontroller to create a digital clock.  The clock will be able to save time when disconnected from power, and it can be powered from a USB connection or from the wall outlet.  The clock displays the hours, minutes, and seconds with an AM/PM indicator.  […]

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 […]
