Home TV, air-conditioning appliances are infrared remote control, This experiment is to see the principle of its reception and emission. So two blocks of Arduino Uno are required to receive launch separately. The reception of the Arduino Uno Infrared remote control (in this article) Next, Arduino Uno Infrared remote control receiving and transmitting signal exp

First, preface:In the above, the author systematically expounds the two driving modes of 1602, and simply mentions the Liquidcrystal Library of Arduino. In this article, the following two questions are explored in more depth: how can I minimize the 1602-to-Arduino port footprint? How should the Liquidcrystal library learn? Under the Arduino LCD1602 Comprehensive

The article once introduced how to use the RF module to implement wireless control over Arduino. Its principle is very similar to that of remote control, which can implement RF wireless remote control with four buttons. HoweverThis solution is not suitable for data transmission scenarios. For example, you need to transmit the value of the light sensor collected by Arduino to the PC end wirelessly. Technical

Always heard that many do IoT, smart Home controller using the Arduino, studied brother there got an Arduino development board, a afternoon study, feel this suitable for children play:)Talk less, sum up, it is easy to use later. I mainly refer to the Baidu Library of a 60+ page of "Arduino from scratch" and some technical forums such as Geek Workshop bar. As a re

Translated from: http://ricardo-dias.com/2010/11/20/arduino-wakes-my-pc/I've always dreamed of controlling something in my room through the Internet. Watch IPTV on the computer, turn on/off the lights, remote control peer download ... To do this, I need a server – my old desktop can do it. Of course, I didn't mean to hang it all day/week/month ... ^^I need to find a way to revive it whenever I want to. So I think I can use an

Author: huaqing visionary lecturer Before we use Arduino to achieve the lighting, flashing lights, serial lighting and the combination with the upper computer lighting. This time we will implement a UDP server to accept the command to implement the lighting, and to use the Intel Edison Development Board to achieve the lighting. First, the implementation of UDP lighting A UDP server is a normal way for network traffic to take. Use UDP protocol to achi

DIY: Using Arduino to make smart home system Intelligent production Geek Fan · 2015-04-29 20:37 (Click on the public number above to quickly follow us) Smart Home System is simply a combination of automation control system, computer network system and network communication technology in one of the networked intelligent home control system. This article shows the smart Home system can be indoor and outdoor temperature, weather changes and door an
