ArduPower – remote control AC devices over Ethernet

Alberto Panu has designed this Arduino-based project to remotely control a bank of AC household current outlets through an Ethernet network. The project uses an Arduino Uno, Ethernet shield, ULN2003 Darlington transistor array along with six power relays and a handful of discrete components. The AC outlets are controlled based upon Telnet commands and the […]

Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data

This Instructable  describes a prototype of a road condition scanner using Arduino + GPS + SD + Accelerometer designed by TechBitar: I thought it would be educational to build a prototype that I can take on the road to log, geo-tag, and time-stamp sensors data to be analyzed later with mapping and data analyses applications.  […]

Winston writes: I have no involvement in this project, but I think it deserves to be The standard for Arduino interconnectivity smARtDUINO support ELECTRIC IMP!!! The cheapest and easiest solution to create the Internet of the things. smARtDUINO is the most advanced platform for the creation of electronic projects and even products. It is the […]

GOduino III – the breadboard-friendly Arduino-based robot controller

Techbitar wrote this Instructable detailing the build of his GOduino III – the breadboard-friendly Arduino-based robot controller. We previously covered the GOduino II. The GOduino III is based on the ATmega328p microcontroller and the L293D dual h-bridge. It’s built with DIP ICs and through-hole components for ease of assembly and repair.  This robot controller can handle […]

Minimalist Arduino for $3

What’s the fewest components you need to have a functional Arduino? Wolf Paulus gets it down to just an Atmega168 chip, power connector and LED for good measure. He describes, “This is probably the most minimal ATmega168-20PU based Arduino you can come up with. The ATmega168 (available for about $3) was the default Arduino chip […]

Arduino based stage design

Like large things that light up? Here’s a Arduino based stage design consisting of eight large wooden letters lighted by 110 LED modules. Arduino and application code are released on GitHub. I made with some friends an Arduino based Stage Design: eight 80cm high wooden let­ters and 110 Led modules controlled by a Processing application. […]

Webcast today: Arduino controlled robots

O’Reilly is offering a free webcast on Making Arduino Controlled Robots. The one hour presentation is scheduled for Tuesday, October 30, 2012 (yes, that’s today — short notice) at 10 AM PT and features Michael Margolis, author of the Making an Arduino-Controlled Robot. The presentation focuses on sensors and motor controllers in Arduino projects with […]

Tutorial: Arduino as barebones AVR programmer

Michael Holachek of HCIL Hackerspace has produced this 10 minute video tutorial that explains how to program a barebones AVR with an Arduino. This is a well explained how-to with clear video will be helpful to newcomers and Arduino veterans alike. Go to Michael’s website for code, resources, and more. Via the contact form.

Breadboard with an integrated Arduino

BizzyBee breadboard is a simple concept. Take an Arduino, and stick it into the breadboard. You get access to the Arduino pins through a header sticking out of the center of the breadboard. The concept is modular, with an FTDI and power board add on, and a separate Arduino shield compatible breakout board. Via Electronics […]

Lean, efficient I2C LCD Arduino library

Sam from lincomatic has released his new I2C LCD Arduino library. Known as LiquidTWI2, its a lean, high speed I2C LCD Library representing an extension of the work done by FalconFour on his LiquidTWI library, with the addition of support for Arduino 1.0+ and for Adafruit RGB LED Shield (MCP23017-based). Via the contact form.

Magnetic loop antenna controlled by Arduino

This video by Ricardo Caratti demonstrates his method for controlling a Magnetic Loop antenna with an Arduino. The antenna’s tuning capacitor is adjusted using a stepper motor interfaced with the Arduino equipped to read IR commands sent from a compatible IR remote control. This allows the tuning capacitor to rotate clockwise and counterclockwise. Due to […]

GUINO Arduino GUI visualizer/debugger

madshobye devised this graphical debugging console for Arduino while serving as an artist in residence at Instructables. He wanted a graphical means of visualizing what was occurring in an Arduino program. “It can be a tricky task to debug and visualize realtime data on the Arduino board. You are usually stuck with the standard serial […]

I2C multiplexer shield controls 8 independent I2C buses

Sometimes I2C addresses can over lap, or maybe you need to use more than one of the same device. The I2C multiplexer shield is a way to control 8 I2C buses from a single I2C peripheral on a microcontroller. Voltage translation is also handled by the multiplexer chip. It was built on an Arduino shield […]

ActiviTea – physical data-scraping in action

The crew from Imagination Labs wanted to track the number of cups of tea consumed at their office. They designed Activitea, a project incorporating a series of sensors placed throughout the London Imagination office that count the cups of hot drinks made in every kitchen. “The prototype consists of 3 objects: 1. A ‘tea counter’ […]

BrewPi open source brewing controller

Here’s an interesting project to automate your home beermaking process. “BrewPi is an open source fermentation controller that runs on an Arduino (for now) and a Raspberry Pi. It can control your beer temperature with 0.1 degree precision, log temperature data in nice graphs and is fully configurable from a web interface.” The Arduino is […]

Driving 4 8×8 LED matrices via the HT1632C and an Arduino

Luca wrote a tutorial on how to drive four 8×8 LED matrices connected to the HT1632C IC via the Arduino. The HT1632C is a LED driver IC capable of controlling 256 LEDs. It uses a custom 3pin serial interface. The Arduino sketch for the demonstration displayed in the video is available.
