Arduino npn transistor switch circuit

Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Similar to eBay, sellers on Aliexpress can be either companies or individuals. Aliexpress is different to Amazon because it acts only as an e-commerce platform and doesn’t sell products directly to consumers.

Smart Living Room (Home Theatre)


I built myself a voice controlled home theatre, with background light, screen and projector control. With an ESP8266 and an Arduino Nano. I\'ve got my girlfriend an Amazon Echo device for Christmas. Some days later I thought that this device on its own, is a little boring. So I promised her to make us a voice controlled smart living room... and this is my way to it.

A DIY Smart Insole to Check Your Pressure Distribution
A DIY Smart Insole to Check Your Pressure Distribution

Pressure measurement is already used in a variety of situations. It provides information about gait mechanics and has a wide range of applications, i.e. in clinical situations and in sports. In this project the sensors are used to gain insight about weight distribution. Real-time visualization of pressure mapping is also incorporated because it makes it much easier to understand your data.

Arduino Indoor Garden
