This article is copied directly from the forum and can be accessed by clicking on the Forum link .I. OverviewAlso do not understand the project submission format, refer to other projects have been submitted in the format.Look at the project of the great God, I can only say that the heavy participation to comfort themselves, to their courage. Let's call it a small production, the project is too big on the name of the match AH.Contact Arduino for three

Arduino Peripheral Modules: analog-to-digital conversion of sensor components (thermo-sensitive, photosensitive, wet-sensitive) ArduinoFor Arduino, it only knows digital, and the analogue is a "foreign language".Analog: Both time and value are continuous physical quantities.Digital quantity: Both time and value are discrete physical quantities.The analog-to-digital conversion circuit is capable of convertin

1, download and unzip the software, small series is extracted to the desktop, we can not do so, small series is just a demonstration, because the small part is not used this. Then open the folder. As shown in Figure 1. Figure 1 2, find "Arduino.exe", double-click "Arduino.exe" to run. The main interface of the Arduino will appear. As shown in Figure 2. Figure 2 Figure 2 provides a simple functional callout for the

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

This is an article on the hands-on production based on Arduino and 12864 LCD module graphical display of GPS navigation system posts, works and costs may not be comparable with TB navigation products, but the hands-on process will bring you fun and knowledge. You should have some background knowledge before you do it:1. Arduino related Foundation;2. Can use 12864 LCD module;3. Can use

sensor detects a move and the output is high, if the human body continues to move within the detection range, the sensor remains high, knowing that the person leaves before the delay turns the high level to low.differenceThe difference between the two detection modes, after detecting the movement trigger, if the human body continues to move, whether the continuous output high level. hc-sr501 simple function Experiment Next, we will try to complete a simple experiment to use this sensor.First we

have been very curious about how the Arduino timer is working, recently checked the atmega328p chip data, has now been atmega328p Timer1 timer as a description, control output matching pin D9 output level.The Arduino timer is available in normal mode, CTC mode, Fast PWM mode, and phase-adjustable PWM mode. This article uses the CTC mode, which is when the registerTCNT1 is equal to OCR1A/OCR1B (that is, matc

PreparationI didn't buy the original board. I purchased the compatible board from the authorized supplier. The compatible board has some changes.In order to connect the computer with the source board and the compatible board, you not only need to connect the cable, but also need to download the corresponding driver for the compatible board I purchased to use USB cable connection, the driver depends on the compatible board. Contact the supplier. Note that different drivers are required for differ

: Using the Atmel Atmega168 328 processor, because of its many supporters,The company has developed a 32-bit MCU platform to support Arduino.The current Arduino Control Panel is the latest Arduino Uno, as shown below:Domestic use of more than the Arduino Duemilanove 2009, the main reason isUNO's USB control chip package changes, manufacturing costs rise, other ch

============================================= The first Arduino experiment was a Hello world experiment. Light an LED light, function is to let 13pin of LED lights flash once per second. The Arduino Uno motherboard comes with an LED light on the 13pin, which allows us to do some system diagnostic tests. Hardware: Arduino UNO R3 2012 motherboard piece, $52

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

Arduino Data type Conversion How to easily play Arduino SCM, when I was in the data conversion, encountered a problem, try C language and C + + many functions, did not achieve the float data conversion to char type. After hard access to the data, finally found a great god-level function!!! DTOSTRF (), you can easily implement data types from float to char. Get it The format is as follows: char* DTOSTRF (

ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many innovative projects, so in this tutorial we

In this project, I'll show you how the Arduino connects to the alcohol detection sensor. Here, I have designed an Arduino Shield circuit board using the Easyeda online PCB designer. The Arduino Alcohol Analyzer detects the amount of alcohol in the breath, and then, by some calculations in the code, we can calculate the amount of alcohol in the breath or blood, an
