While this is not the first Arduino based GPS Data Logger out there, it may be the most versatile. This device has a lot of features & even more possible uses. It started with significant inspiration from Mikal Hart’s “Reverse Geocache”TM and the …
Builda digital clock that turns AC load on/off with preset time. sourcecode with sdcc for 8051. The Clock Controller V1.1was designed to be an exemplary of using ‘C’ language to control timer0interrupt, 7-segment LED and keypad scanning. It provides 1-bit sink currentdriving output, for driving a relay, opto-triac, say. Many projects requiring7-segment display and keypad interfacing …

To see how RFM12B wireless compares to other similar wireless options (e.g Xbee, XRF etc..) check out this well compiled comparison overview by Stuart Poulton: http://blog.homelabs.org.uk/wireless-connectivity/. Overview Made by Hope RF, re-branded by RFsolutions in the UK. Sometimes called ‘Alpha RF’ Low cost RF transceiver (from Rapid, Farnell, or RS in the UK) Up to 300m transmission Up …

TL;DR – I wanted all of my AV components to turn on and change inputs as soon as I started Airplaying music to my Apple TV from my iPhone, so I popped open the Apple TV, wired up a photocell sensor to an Arduino Uno, wired up some Infrared LEDs, wrote some code, and made it …
I had one remote controlled project that needed an Arduino running 24/7 but I didn’t want to leave my $32 Arduino UNO, so I decided to buy some pieces and created my own Arduino. The most important part was buying the microcontroller. These were my options: ATMega328P-PU with Optiboot ~ $5.50 (Sparkfun) / $5.19 (Digikey) …

Growing plants is fun and watering and caring for them is not really a hassle. Microcontroller applications to monitor their health are all over the internet and the inspiration for their design comes from plant’s static nature and the ease of monitoring something that doesn’t run around and sweat. I am relatively new to plant …

Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use. …
This instructable goes through how to design and print a variety of 3D models using a system called the ‘UCube’. Note: I would love to eventually publish detailed instructions on how to make your own UCube, but since the design is still changing and improving, this post will gloss over a lot of those details …

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 …
