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 […]
In this post I’d like to describe you a project I’m working on that consists of connecting an Android development board to one (or more) Arduino slave(s) using modbus protocol and rs485. Even though the idea of this project could be applied in many fields, I chose to contextualize it in a typical smart home […]
Dimmer With MOSFET This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A) in a diode bridge is used to control the voltage across an incandescent bulb with pulse-width modulation (PWM). The power supply voltage for driving the gate is […]
This is a simple guide on how to make a Ultrasonic sensor arduino mega with code, an HC-SRO4 Ultrasonic Sensor, a Buzzer, and some leds. The ultimate goal of this tutorial is to use the buzzer and LEDs to display how far the object is from the ultrasonic sensor. Step 1: Materials Needed The Materials […]
