What if making an Arduino, or wiring up an Arduino was as easy as printing one out? In this tutorial we printed our own Arduino Pro Mini board using a pen plotter and the Electroninks Circuit Scribe (a rollerball pen with highly conductive ink). Within 15 minutes we printed the board, placed components down with […]

Ventilation, air conditioning (HVAC), or any other applications, where a pressure or a flow of air (gas) is essential, can be precisely regulated only if we know a real pressure/ flow conditions. Monitoring of fans functionality, status of filters, …, even for this purpose are very suitable differential pressure sensors from Swiss company Sensirion with […]

I was always impressed by the Daft Punk Coffee Table.  Being able to light up a bunch of LEDs and flash them in patterns has so many applications.  It was one of the reasons why I bought an Arduino seeing how it could control a matrix of LED lights.This is my attempt at building the […]

INTRODUCTION This manual will show you how to use each of the components in the kit, and give you software Sketch examples for each one. Then you can combine some components to make examples of Automatic Systems such as a lighting controller.   You’re probably here because you’re interested in MAKING things with Arduino. The […]

Abstract: This design idea presents an integrated IF voltage-controlled oscillator (VCO) that can retransmit the audio signal from a cell phone to the FM broadcast band. By placing the cell phone’s speaker near the microphone, the user can use the phone as a hands-free device while driving. The circuit in Figure 1 can retransmit the audio […]

I don’t get up at the same time every day, so I thought it’d be nice to have an alarm clock that would drag me out of bed at different times on different days. That was the initial idea: things got out of hand, of course, and this is the result. What it does: 1) […]

This is a DIY variable resistor I created as an interface for live performance– like a stomp box. I designed it as a project my audio students could build with materials we already have in the classroom. The result is a variable resistor that can be triggered with just a little pressure from hands or […]

I’ve had a cuecat barcode scanner sitting around for over 10 years. Basically it connects to a PS2 port (apparently there is a USB version) like a keyboard and spits out a barcode when scanned. Nice!. The annoying thing is that it is “encrypted”. What I set out to do is; – unencrypt the barcode […]

In this introduction I will show you a overview of this project whit Arduino Uno.  The purpose of this instructable is move a electric roller shutter by Arduino Uno. The prototype that I made is my first electronic project with Arduino and I hope this instructable and the solutions that I found are useful for […]

To measure my electricity usage I decided to build a small system that would count LED blinks on my power meter which indicate the used Wh. It was pretty straight forward system requiring an Internet connected microcontroller to log the data and some sort of sensor that would detect LED blinks on the power meter […]
