Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an

Desde BricoGeek nos llega la noticia de la celebración de una nueva Barcamp, esta vez en Vigo. La reunión perfecta para cacharrear y debatir entre amigos sobre temas como el Open Hardware, Arduino o impresoras 3D entre otros muchos, y puede que con alguna que otra sorpresa. Unas jornadas DIY muy interesantes que tendrán

This example shows how to use SPI communications to read data from a SCP1000 Barometric Pressure sensor, and how to then post that data to the web by using your Arduino/Ethernet Shield combo as a simple web server. Using the Ethernet library, your device will be able to answer HTTP requests by responding with just

Have your ever seen any of “Ben Hecks” portable console builds? Well if you haven’t, he often uses these Chinese Famicom clone consoles. These cloned consoles are often times refered to as NOAC’s, meaning NES On A Chip. They are called this because they are a fully functional Nintendo Entertainment System literally on one chip.

Concept: I would like to make a jacket that has a small LCD screen to create subtexts for interpersonal human interaction. The user would use a limited “keyboard” with force sensors and buttons under soft silicone keys to create computer textual subtitles to human interaction (textual emoticons, ie: :P). The dichotomy between personal interaction that

In this tutorial we make an LCD shield for using 20 character by four row LCD modules with Arduino Uno. Updated 18/03/2013 In this article you can follow the process of making another LCD shield for the Arduino Uno or compatible boards. In the past (which explains the word another in this title) I made a 16 x 2

Chris, from PyroElectro.com, proposes a comprehensive tutorial on how to make a simple, yet effective, Arduino-based tachometer. The circuit is very simple: an IR led is coupled with an IR phototransistor to detect possible interruptions of the light beam, while the Arduino is responsible to calculate the time interval between two such events. Finally, a LCD is used to

I am submitting this instructable to the Arduino challenge. Please remember to vote! My neighbor had a little problem with his cat. It want’s to go out and back inside too frequently. Usually he opens just his kitchen window and let’s the cat in/out. Usually the cat stays only short periods outside and want’s soon
Arduino controlled window for cat Continue Reading
Here is my instructable on how to construct a pretty simple (for some!) short range infrared rangefinder/range sensor. Infrared rangefinders are very useful in a number of projects. The majority of these come from obstacle detection (in robots) or generally detecting distances! The one shown here is only a simple rangefinder and will only really

Hello, This time I will show an application of the infrared sensor module with Arduino. This module (composed of a pair of LEDs, a infrared transmitter and a receiver and an IC that generates a frequency modulated) is generally used to detect obstacles in robots. This module has some advantages over a simple LED emitting
