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 […]

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 […]

Today I want to make a LED Scroll Bar as the above picture showed. Ten LED strips can flash in different effects by using a control board. Required Components LED strip, Arduino Nano, Dupont line and a control board. So, how to make a LED Scroll Bar? Step 1) Cut the LED strip into 10 […]


Traffic light and pedestrian crossing implemented with an Arduino

Posted on: 13 Jul 2016

This video shows the Traffic light and pedestrian crossing I’ve implemented with an Arduino. It’s a reproduction of the crossing near my home, timings taken from a video of it. Incidentally, I produced the diagrams for this using a product called Fritzing.  It’s a nifty piece of software that allows you to draw a breadboarded version of […]
