When programming to Arduino, because there is no debugging tools, often through the use of serial communication to call Serial.print and SERIAL.PRINTLN output Arduino running the relevant information, and then on the computer with the Arduino The IDE's serial monitor to see the print out information. Serial Monitor not only accepts data that

Reprinted please indicate the source: http://blog.csdn.net/lxk7280 First, give a preliminary understanding of the main things to be used. There are two categories: hardware and software. Hardware, that is, Kinect. Software, I .e., Arduino and processing. Arduibo is believed to have been used by many people. Many electronic products such as robots and quad-axis aerial vehicles are related to the romantic compiler of

Arduinoyun Tutorial of Arduino programming environment to build Arduino programming environmentIn general, what we call Arduino is a development board that we can actually see, which can be Arduino UNO, Arduino Yun, Arduino Mega,

Hello everyone, I'm a small-story,Remember the previous section click the Open linkWe're talking about the Arduino Foundation today.First download the program on the Arduino official website.Windows Decompression versionVersion of the Apple systemOK, download the programming software. Let's just talk about programming.This is a programming language similar to C + +.void Setup () { }This is the initial stat

Arduino car entry-fourth day (sensor), arduino car Hello everyone, I am a small Editor. Record the content in the previous section and click "open link ". Today we will talk about sensors. Today we will talk about light and ultrasound. Start with a chart: There are three optical interfaces: UCC, out, And GND. Ultrasonic has four interfaces: UCC, T, E, And GND. The following is the principle. The ultrasoni

Arduino MQ135 Gas Sensor first, the wiring The MQ135 has 4 pins, VCC, GND, A0, D0, respectively, where VCC, GND, and A0 are required. The following diagram is a esp8266 wiring diagram. Due to the measurement of the gas value of PPM, it is related to the air temperature and humidity. So we've added a DHT22 here. DHT22 Portal vcc->3v Gnd->g A0->a0 Second, MQ135 lib

I'm with Arduino, and why write this series of articlesArduino has been on fire for years, and it's not a new technology. If someone is not clear about what Arduino is, I'm sorry, please search by yourself, open any Wikipedia introduction or a fan of the series of articles, people introduced more than I know more comprehensive. I'm afraid I don't have to repeat it here.The first contact with
