The role of version Serial.flush () prior to arduino1.0 is to empty the serial cache (dropping received incoming data). But after 1.0 the function of version Serial.flush () is adjusted in order to wait for the serial port data to be transmitted (Waits for the transmission of outgoing Serial data to complete.) (Referenced from http:// Arduino.cc/en/serial/flush).Because I am in the process of using Wifibee, if both want to use serial.print through the serial port to the WiFi module to send instr

Source of demand1. My son finished the year 6 years old, like to play fireworks, but the courage is small, so I am responsible for ignition, from the year before 26 to the beginning of eight, every night to give his son point firecrackers ah point firecrackers.2. The new year to open the door gun and opened the gun, Lunar New Year early morning also to help mom point firecrackers, said the whole string of small firecrackers also fried too fast, every time did not run a few steps on the open, bro

First Arduino default I²c address is 7-bit address, the manual is described, 7-bit address is 0x1e, read address is 0x3d = (7-bit address If you want to communicate with the hmc5883l, you need to hmc5883l power on the 5ms. Therefore, the general write configuration requires a delay of 5ms before communication. After connecting the device to test the sensor, identify the operation and identify register a, identify register B, identify register C is

Recently suddenly want to study STM32, see almost all of the tutorials are used in C-Series microcontroller program, so that has been studying C 艹 I write very not adapt to, today studied for a noon, successfully a single LED driver package into an Arduino-style class library, the use is very convenient, the method is as follows.Before you begin, it is recommended that you follow the methods described in this article in the STM32 template creation met

Arduino relatedArticleNow, I recently bought a Bluetooth chip (bluetooth module JY-MCU) online, which is also 37 yuan cheaper This chip uses the Bluetooth serial port service, which is encapsulated by Arduino. That is, the connection line reads data and writes data through the serial API,ProgramCodeIt is also very simple The only trouble is that you can write applications on your mobile phone. I

Arduino Port Code: int red=255; Create variables to store the data to be sent int green = 2; int blue = 3; void Setup () { serial.begin (9600);//define a data transfer rate of 9600 bits } void Loop () { serial.print (red); Serial.print (","); Serial.print (green); Serial.print (","); Serial.print (blue); Serial.print ("\ n"); Delay (+); } Above red, Green,blue is replaced with the value obtained by the color sensor in the actual app

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.

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
