The radio has been in use for a long time, and for a long time it was born a group called the Ham Tribe (^_^ cq), the man who ate ham all day. Radio and the Internet: There are also some security risks, such as: in the transmission of wireless signal does not take into account the CRC check, encryption and other security issues.Small scenario: If you use the Wireless key card to unlock the car on one day and press the second time to unlock it, then your car has been targeted by hackers!A new att
Small white write programs are used eclipse, so learning Arduino naturally want to use eclipse, because I lazy, so convenient. Online to find some posts to see, feel the development environment is more troublesome, this does not conform to my lazy style, so I made a simple point.The first step: Download a variety of things1, JDK, this goes to the Oracle official website is good (in fact, Baidu download faster) Http://download.oracle.com/otn-pub/java/j
Arduino is a convenient, flexible and easy-to-access open source electronic prototyping platform. Includes hardware (various models of Arduino board) and software (Arduino IDE). Smaller than raspberry (Raspberry Pi), but still powerful. It is built on the open source simple I/O interface version and has a processing/wiring development environment that uses Java-l

When there is a theft incident in the community, do you always worry about the theft of your home on the subway at work, in front of your computer at work station, during a late night gathering, or when you are traveling?Now let's talk about how to DIY an Arduino-based home anti-leech!Before DIY, design the DIY process first! In order to express myself in a concise way, I can paste my own picture! In my opinion, the original intention of DIY is to use
0x00 IntroductionThis article wants to describe the production process of Arduino version Badusb in a simpler way. I know that before this has been a lot of predecessors have written related articles, but small white may also be a little confused, so this article is a quick introduction to understand, I am also a dish b big God do not spray, thank you ~.
"BadUSB" is one of the hottest topics in computer security, discovered jointly by Karsten
DescribeAn Apple Watch and iphone app for controlling any infrared device. The iOS app sends an HTTP request to one or more Arduino with an Ethernet board. Arduino is parsing an HTTP request and sending an infrared signal. The Arduino code is based on the Irremote Library (https://github.com/shirriff/Arduino-IRremote).

ReasonThere are a number of tutorials on the network that allow the Arduino 5V level to be converted to 3.3V levels, and to communicate with the chips working in 3.3V. But if you want to drive a chip above 5V, you can't find the tutorial. So today I'm going to introduce a way to get Arduino's output port to drive an electronic component that needs 5~12v input. The following is an example of 12V.Effect

2.1 Obtaining schematics and PCB boardsLearning Arduino necessarily need to have an Arduino board, either buy or make their own, because the Arduino website provides each type of schematic and PCB, so the production is very convenient. The following is the production of our Arduino UNO Compatibility board Sagoo Uno. We
