USM-MEMS-VOC module evaluates rate of air pollution by contaminants such as cigarette smoke and cooking odors and allows control of air ventilation system on demand. Modul USM-MEMS-VOC is based on the innovative and highly stable TGS 8100 MEMS semiconductor sensor TGS8100 from...

This project automatically switches off the electrical flow in event of excess heating or excess cooling thus protecting the circuit from damage using NXP NCX2220GU. The comparator guarantees to operate at low voltages which makes this device convenient for use in 5 V systems and has...

by Martin Cooke @ elektormagazine.com: The latest MEMs device from STMicroelectronics is said to be the world's most advanced six-axis motion-sensor device designed to support image stabilization in smartphones, tablets and digital still cameras. The LSM6DS3H combines a 3-axis...

by nusnel @ instructables.com: For my monthly maker column in Dutch newspaper "De Volkskrant", I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three...

by oliverb @ instructables.com: The Arduino controls a Geared Stepper Motor 28BYJ-48 via a ULN2003 Stepper Motor Driver Board. The 4x20 I2C LCD display and 5 micro switches form the interface to the Arduino. The controller has a Manfrotto 200PL-14 quick release tripod mount for...

In this article we will discuss about the various types of diodes, their working principle and their common uses. We will cover many common diode types, such as P-N junction diode, Zener diode, Schottky diode, LED and laser diodes, photo diode, varactor diode, avalanche diode, PIN diode...

Emanuele @ dev.emcelettronica.com published an article on how to drive LEDs: The LEDs (Light Emitting Diode) are diodes whose basic characteristic is the ability to emit light when they are passed through a current that flows from P to N region. At each recombination between the...
