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

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

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
