The E-Taster Assistance System with Lab-on-Spoon and Lab-on Fork as ‘Electronic Tongues’
Posted on: 23 Jul 2016
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 […]
Interfacing an Arduino with LCDs
Posted on: 22 Jul 2016
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 […]
Midi VU meter, LM3914, Arduino, PWM
Posted on: 21 Jul 2016
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 […]
Arduino Event-Driven Universal AV Remote
Posted on: 20 Jul 2016
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 […]
Android Arduino Communication through Modbus and Rs485
Posted on: 19 Jul 2016
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 […]
Safe and simple AC PWM Dimmer for arduino / Raspberry pi
Posted on: 18 Jul 2016
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 […]
Ultrasonic sensor arduino mega with code
Posted on: 18 Jul 2016
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 […]
Displaying Arduino data
Posted on: 17 Jul 2016
Arduino temperature display I’ve had an Arduino-based weather station since June 2009, but one problem with it has been that there hasn’t been any easy way to display the data in real time without going to the database (or the raw import files) to see what the latest observations were. I wrote a quick web […]
Arduino – Cannot get ECG readings from heart, but I do when I poke at the leads
Posted on: 16 Jul 2016
down vote favorite I have a minor issue with my ECG. When I poke at the leads, I get a reading. But when I hold the leads or place it near my heart, I don’t get anything. I’m pretty sure this is hardware related, but I don’t want to completely rule out a potential software […]
Pololu Wixel Shield for Arduino User’s Guide
Posted on: 15 Jul 2016
1. Overview The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to replace your Arduino’s USB interface, which means you can use the standard Arduino computer software to: wirelessly program the Arduino (this feature is not available with the Arduino Leonardo or the A-Star 32U4 Prime). wirelessly debug sketches with […]
