exploring arduino

Arduino is an open source hardware, since 2005, has been slowly upgrading, now known as the Arduino circuit board has been many, and every day is increasing. Currently the most common are Arduino uno and Arduino Mega 2560. The Arduino circuit board is traditionally based on

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

This article applies only if the bootloader is damaged and the purchase of a home-made usbasp download line causes the IDE to be unable to recognize and not burn the write. is a slightly non-mainstream mode of operation.Because the Arduino IDE does not support this free-drive usbasp line, it will prompt for errors.The whole thing is like this:1. SymptomsWith the Arduino control servo inadvertently play off,

Arduino uploads data to shell Iot platform and interacts with FPGA. arduinofpga This article implements the interaction between Arduino and FPGA. Of course, there is no new protocol, or it is based on serial communication. Now, learning a serial communication can basically drive most modules, moreover, it can seamlessly interact with various single-chip microcomputer data. Because of its powerful Library Fu

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

Intelligent Robot Introduction: Amarino is an interesting application platform that enables connections between Android phones and Arduino. Currently, there are many plug-ins Based on amarino to solve various problems. And it is an open-source project. Amarino is basically composed of three main parts: Android applications are called "amarino" The Arduino library is called "meetandroid" Amarino plug-in

Just getting started with Arduino, very good. Arduino ide I used version 0022 at the beginning, and its editor was really uncomfortable. I didn't prompt that auto-completion was not completed. Because I have been using eclipse for development, I am looking for a solution. My board is Arduino uno .. According to the official method, there is no result .... Accordi

I love Arduino nano–. This is a very small but fully functional Arduino Uno. However, when I went to connect it to the Internet, all the neat and small also disappeared under the large-size Ethernet shield.However, I recently found a better, more compact way to connect my nano to the Internet – by using Wiznet Company's much smaller (and cheaper) Wiz550io module!If you want to make it easy to connect, you c

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
