Arduino uno input impedance

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.

Arduino LIDAR
Arduino LIDAR


LIDAR (Light Detection and Ranging) is an optical remote sensing system which can measure the distance of a target by illuminating it with light. LIDAR technology is being used in Robotics for the perception of the environment as well as object classification.

DIY Arduino Weather Station

This is our original weather station kit. You will be surprised how much you can learn from it, such as how to connect sensors and write program to read the data, and display it on a LCD display. What you can do with this kit is only limited by your imagination. 

Rings of Saturn LED Music Visualizing Pendant Light
Rings of Saturn LED Music Visualizing Pendant Light


I made this LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music syncing had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips.

Smart Living Room (Home Theatre)
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.

NeoPixel Lightsabers w/ Party Modes -- Arduino-Controlled
NeoPixel Lightsabers w/ Party Modes -- Arduino-Controlled


This project started as part of my Halloween costume, and then expanded...a lot. I ended up making two lightsabers - a Kylo Ren style saber and a Rey / Anakin Skywalker style saber, and creating different Arduino code to simulate each. And, I decided to go beyond the normal lightsaber, and create a party mode with colorful animations on the saber.

Digital & Binary Clock In 8 Digits x 7 Segments LED Display


This is my upgraded version of a Digital & Binary Clock using an 8 Digit x 7 Segment LED Display.
I like to give new features for usual devices, specially clocks, and in this case the use of 7 Seg display for Binary Clock is unconventional and it is an interesting and a different way of applying it.
