This article is produced by @ray, reprint please indicate the source. article link:http://blog.csdn.net/wz22881916/article/details/78161080 This year, our team selected the B problem, ball control system. Finally, we got the province special and the country one, also was to finish my big moment's wish. The following is a summary of the game, and later recalled when there is a thought. The ball-rolling control system is a multivariable and nonlinear control object, and is a two-dimensional extens

Similarities and differences between Arduino and C + + The cause is this: I want to play Arduino, play for a while, I would like to write some of their own library, easy to operate. So the cheap in C + + wrote a library, the results found below a few points, a little chaos, only for memory and reference: (the direction is changed from C + + to Arduino) string rf

Memsic2125 Acceleration Meter MEMSIC2125 is a two-axis accelerometer that can measure the acceleration of positive or negative 2g in two directions (g represents the gravitational acceleration). Its pin design is simple: Only two data output pins, one for the x axis and one for the Y axis. Its data output pins will output different pulse widths according to the size of the acceleration (do not know what the pulse width is please see this article). The subtle level of pulse width can be measured

Today took out the home Arduino again out to play a bit, also looked at some recent online information. Feel the current online article still stay in this how to use, that how to use the stage. There are few examples of the combination. So, I will write the code today, for everyone to refer to the brick. Arduino, after all, is the basis of C language. So the structure of the program is still very important.

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

I think you will see the URL below my first article, the official website of Arduino. When you go in, you will see the following picture: it already contains various versions, including Windows, MacOSX, and Linux, you can download the corresponding version based on your computer system. I use Windows XP. You can install the software. After installation I think you will see the URL below my first article, the official website of

after the module test, make sure the ESP8266 is working properly and start connecting with Arduino to upload the data detected by the DHT11 temperature and humidity sensor to the monitoring platform. Prior to understand the platform has Yeelink and thingspeak, the principle should be the same, I choose Thingspeak here, we can try Yeelink, welcome to provide learning to share. put the results first. Welcome visit: https://thingspeak.com/channels/29665

calibration of analog signals This example shows you a technique for calibrating a sensor: Read the sensor value for 5 seconds at startup, then look for its maximum and minimum value. The maximum and minimum values after calibration will be useful in the map function. complete the hardware device required for this example Arduino Board or Genuino board LED Analog signal sensor (photoresistors on OK) 10kω Resistor 220
