Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and

L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context – be it a server, phone, router or other monitorable device. The visual transformations represent various characteristics of these entities, such as

After I got comfortable programming and building with an Arduino, I used my newly acquire microcontroller skills to build a robot. Using a microcontroller, four high-torque DC gear motors, spiked legs, a linear actuator, rotation sensors, and 3 L298 H-bridge circuits, this robot can climb up trees of varying diameter. The very long build log

Domenica 17 Giugno alle Officine Arduino una quarantina di persone hanno dimostrato la veridicita’ dell’affermazione di S. Levy. Dall’anno scorso Arduino organizza in Italia l’Arduino Camp , un evento di due giorni che vede il primo giorno dedicato a presentazioni e talk su Arduino, seguito da un secondo giorno di Hack Day su un tema.

One-time-password (OTP) and its time-based version (time-based OTP, or simply TOTP) are commodity solutions to provide a second factor, in addition to simple passwords, for authentication. Here Jose Damico proposes his way to implement a simple TOTP device using only open-source tools. The core of the project is an Arduino board connected to a small

The dryer in our house is in an out-of-the-way corner where it’s hard to hear the buzzer. When we miss it, the clothes sit in the dryer getting wrinkly, so we start the dryer again, don’t hear the buzzer again … it’s an endless cycle. After what seemed like the thousandth time, my wife quipped,

We are happy to announce the first wearable kit on the Arduino Store . This kit has been made by Plug’n’Wear specifically for us. All fabrics in this kit are produced in Italy, and strongly related to a textile family business. If you want to get deeper into the story of this product have a

This is partially me sharing this technique, and partially me learning how to use Instructables. If there are issues with my documentation of the technique or my use of Instructables, please let me know in the comments – thanks! I needed a long row of switches in a pinch, and didn’t have nearly enough switches

Nick Poole, from SparkFun, proposes this nice tutorial, where detailed instructions on how to connect a radio-controlled (RC) remote to an Arduino board are described in great detail. RC remotes are very simple controller, typically used to wirelessly control electrical rovers, cars and planes. Depending on the number of degrees of freedom required by the

Samuel Cox, a maker who defined himself as a mix of “design, ideas and technology“, has invented a brand-new competition for digital citizens: Digilympics. From his website: Under the hood, this funny race is enabled by a Processing sketch that seeks for Twitter replies on each account: a new reply triggers a motor-shield equipped Arduino
