HexiLogger, an Arduino based data logger using ATmega328

The purpose of this project was to create a simple, portable device that would periodically read sensors and then store the sensor data so it could be retrieved later. The result is the HexiLogger, “hexi” because it can support up to six different sensor inputs and “logger” because it will store the input data on

Arduino – Modifying a Robot Arm using ATmega328

Essentially another tutorial involving controlling DC motors. In this post I’m going to first alter a robot arm I had built previously from a beginners kit so that it can be controlled from Arduino. Then I’m going to write a series of posts on different ways to control the robot arm using Processing and other

Lira: A Barebones, Low-Cost, Arduino Compatible Atmega328 Breakout Board

What I came up with is the Lira. It is, as you will see, little more than a breakout board for the ATmega328, but it provides all the bare necessities like voltage regulation, basic power conditioning and an FTDI programming interface. It’s the smallest, simplest, cheapest design I could come up with that still uses

Analog audio panel for PC using ATMega328 microcontroller

Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conference calls using PC. The first thing I wonder always when starting is if my audio settings — mic volume,

Energy Monitoring Transmitter using Atmega328 microcontroller

This energy monitoring transmitter, known as emonTx, is an Atmega328-based small wireless energy monitoring node. It also fully compatible with Arduino IDE. EmonTx is designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. The design is based on the JeeNodeV5 by Jean-Claude Wippler and

The $9 Quasi-duino (Almost-duino) using ATmega328 microcontroll

Do you currently have an Arduino and want to make it smaller for cheap?  The Quasi-duino is for you (Italian for almost-duino).  This makes a functional “almost” Arduino, in a very small form factor using the narcoleptic library for pico-power operations on a pico-space breadboard.  This ‘ible will use Arduino 1.0.  All of your Arduino
