Arduino Sensor Shield

I ordered some time ago Arduino Sensor Shield v4.0 because it is an easy way to connect input and output devices to Arduino. Arduino Sensor Shield provides three pin (ground, voltage, signal) interface for connecting all kinds of sensors (potentiometer, button, LDR etc.) and output devices (relay cards, servos etc..) to Arduino. The Arduino Sensor

Arduino Yún has WiFi connectivity and Linux

Arduino platform seems to interest many Internet of Things developers. There are now many Arduino compatible platforms with wireless connectivity as you can see in my New interesting Arduino platforms article and it’s comment. Also Google has done some Arduino based IoT. Arduino launches Yún for WiFi connectivity under Linux article tells that Arduino has

Google Arduino based IoT

At I/O, Google Will Be Tracking Things Like Noise Level And Air Quality With Hundreds Of Arduino-Based Sensors article tells that in the blog post, Michael Manoochehri, Developer Programs Engineer, outlines his team’s plan to place hundreds of Arduino-based environmental sensors around the conference space to track things like temperature, noise levels, humidity and air

Tour of the Arduino Manufacturing Facility

Have you ever wondered where all those magical Arduinos come from? Tour of the Arduino Manufacturing Facility article tells that they come from Torino, Italy, and how they are built. The video below will walk you through the PCB manufacuring and assembly process. For more details check also the large set of pictures from Tour


Freeduino is a collaborative open-source project to replicate and publish Arduino-compatible hardware files. The Freeduino Eagle SCH, BRD and Gerber production files allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware.

10 Ways to Destroy an Arduino

10 Ways to Destroy an Arduino article tells how you can accidentally destroy Arduino board. Use a sledgehammer, fire a bullet at it, throw it into a pool….that’s not what we’re talking about. We’re going to show you how to electrically destroy your Arduino: Method #1: Shorting I/O Pins to Ground Method #2: Shorting I/O

RC servo modification for continuous rotation

A standard hobby RC servo motor is designed to rotate through only 180 degrees. They are most often used in RC applications (like steering). The servo motor controlling is done with servo control pulses (1-2 ms pulse at around 50 Hz rate). More details on the control signals can be found at Servo protocol web

DIY Polygraph Machine for April 1

April Fools’ Day is celebrated in many countries on April 1 every year. It is widely recognized and celebrated as a day when people play practical jokes and hoaxes on each other. Lying is awesome way to get people fooled. Here is one idea how to avoid being fooled: use a lying detector. If you’re

New interesting Arduino platforms

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. The microcontroller on the Arduino board is programmed using the Arduino programming language (based on Wiring and C) and the Arduino development environment (based on Processing). This combination of tools have made it a very easy to use platform for all
