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.

Document directory Fading Hardware required Circuit Schematic Code Fading Demonstrates the use of the analogwrite () function in fading an led off and on. analogwrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly, to create a fading effect.

Analogwrite (pin, value) First follow the connection number Circuit This time, we will use Arduino and a set of three-color lamps (red, yellow, and green) to Apply PWM. First, let's take a look at the Arduino board. There are six PWM interfaces in total, they are digital interfaces 3, 5, 6, 9, 10, and 11. For convenience, we use the continuous PWM interfaces 9, 10, and 11. During program writing, we wi

Phprpc + Ruby + Arduino = led turn-on (?) Well, I know this is a very boring sample. For phprpc and Arduino, Google Before reading this demo, please install the SerialPort mentioned in another article. With another gem KIT: phprpc In this example, I established a server through phprpc and called some methods through rpc to control the USB serial port.In this demo, we must establish the server and client.T

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

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
