In one of my last posts I have shown how to drive a servo motor. Servo motors comes in two flavours: the standard servo motors can be set such that they reach a given position and maintain it; the continuous rotation servo can rotate continuously at a given speed. DC motors are very similar to … More Using DC motors with Arduino
In certain cases you may need to use motors for different purposes. Depending on the experiment or the device you are building, the type of motor to use can be different. In this series of posts I will show you how to use those motors with Arduino. Servo Motors Servo motors are motors for which … More Working with motors
This time I’m going to introduce the usage of a kind of magnetic sensors called digital magnetoresistive sensors. Magnetoresistive sensors are based on a property of several materials called magnetoresistance, consisting in the variation of their electrical resistivity when placed in a magnetic field. In practice, the current flow through a magnetoresistive wire depends on … More Using magnetic sensors to make kinematic’s experiments
In my previous post on the subject I showed how to configure the Arduino Ethernet shield, in such a way you can save a lot of memory. Now it’s time to use the shield for something useful. Arduino is mostly used to take data from sensors and to drive actuators to perform actions (such as … More Getting data over the Internet with Arduino
There are words, in Italian, that are not very polite, who becomes funny and acceptable when they change gender. That’s the case for “minchio” (pronounced minkio), used to give a name to something that does not have a name or for which you don’t know it.

Ne sono venuto a conoscenza grazie alla pubblicità esposta un un autobus in servizio che mi precedeva mentre tornavo a casa dal lavoro (vedi foto). La pubblicità mi ha subito colpito per un particolare. Per capire perché è … More Scienza e Arte nell’Anno della Luce
