I’ve been reading a lot about receivers, and it sounds like one important thing is filtering. It makes sense too – simple receivers can suffer from front end overload due to a strong signal. And when on the ham bands, you never know where that strong signal may be – it could be someone driving […]
Introduction In my first article using the Arduino 2009 board, I described a simple temperature sensor interfaced using Visual Basic. I have developed the board and Visual Basic code to give a fairly usable indoor weather station. Overall Operation The Arduino 2009 acts as a standalone weather station. It does not display the data. It […]
At University, Alexander Zenger and I decided to realize a weatherstation with an Arduino Microcontroller. We wanted to measure temperature, pressure and humidity. It should be also possible to get every 5 min a value update on an external server. Our basic idea was to develop a weatherstation which is easy to use with different […]
Since this book was written, Arduino 1.0 was released and Google has changed the Open Accessory standard a lot. At the start of December 2011 Arduino 1.0 was released. This changed a few things, requiring all third-party libraries to be updated. This hasn’t happened yet for the Android Open Accessory ADK. So until this is […]
The Team Kaitlin Schaer as scribe; Bryan Gardiner as tutor; Ruben Markowitz as designer; Anna Failla as integrator Introduction In a time where the logistics of sleep can be all too much to handle, there is a solution! There is a smarter pillow, a pillow that will wake you up just when you need to get […]
In all my arduino projects I was using cheap 1602 LCDs mostly because… they are cheap but also of the libraries flexibility. Recently I found a nice TFT 1.8 inch 128×160 in a very competitive price and i thought to give it a go. Just $4.5. I had a little bit of trouble to make […]
Subject: Daily life activities of food preparation can be challenging for consumers due to restricted skills and experience, loss of perceptive abilities (accident/aging) or due to product fraud and contaminations, commonly summarized under the term of food adulteration, which are exceeding human perceptive abilities in general. Thus, in our work the E-Taster-assistance-system for living assistance […]
Introduction This is the second article in a three part series I am writing on the Arduino hardware platform. This article focuses on wiring an Arduino to a character LCD and a graphic LCD, and includes static and animated demos to show off the capabilities of each display. Character and Graphic LCDs After I initially […]
Hello everybody, I’ve been working on a midi controller for some time now, Midi OUT hasn’t been a problem, but for Midi IN i had to take some more time. i’ve used this circuit for midi input but i’ve used a 4n25: original thread @ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187962258/ it works great! but for my project i need […]
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 […]
