Détecteur optique d'éclairs ou flash pour déclenchement photographique ou flash esclave Mise en garde lors d'une utilisation au cours d'un orage ! Il est évident qu'un orage n'est pas un spectacle offert gratuitement par l'office du tourisme !!! Les dommages occasionnés lors d'une telle activité sont nombreux et sont très souvent accompagnés de blessures, voire de mort lors de leur passage.
There are several ways to save data from a sensor attached to an Arduino. If you’re connected to a personal computer, you can simply send the data from the Arduino to the personal computer serially, and save it to a file. If you’ve got an SD card attached to the microcontroller, you can save the data to the card. Or, if you have access to the internet and a device that can connect to a server, you can save the data to a server. In the tutorial below, you’ll read a DHT11 temperature and humidity sensor and log data in three ways: Serial transmission to a personal computer, and serial capture to a file.Saving data to an SD card mounted on the ArduinoHTTP upload to pachube.com via an Ethernet shield or Ethernet Arduino. code, circuits, & construction | code and fabrication resources for physical computing and networking

Introduction A semiconductor device is one made of silicon or any number of other specially prepared materials designed to exploit the unique properties of electrons in a crystal lattice, where electrons are not as free to move as in a conductor, but are far more mobile than in an insulator. A discrete device is one contained in its own package, not built on a common semiconductor substrate with other components, as is the case with ICs, or integrated circuits. Thus, "discrete semiconductor circuits" are circuits built out of individual semiconductor components, connected together on some kind of circuit board or terminal strip.

The expression of numerical quantities is something we tend to take for granted. This is both a good and a bad thing in the study of electronics. It is good, in that we're accustomed to the use and manipulation of numbers for the many calculations used in analyzing electronic circuits. On the other hand, the particular system of notation we've been taught from grade school onward is not the system used internally in modern electronic computing devices, and learning any different system of notation requires some re-examination of deeply ingrained assumptions. First, we have to distinguish the difference between numbers and the symbols we use to represent numbers. A number is a mathematical quantity, usually correlated in electronics to a physical quantity such as voltage, current, or resistance. Numbers and symbols : NUMERATION SYSTEMS
