how to control servo motor with raspberry pi

Annotated Source: http://www.cnblogs.com/einstein-2014731/p/5551846.htmlThe use of the C language Control Raspberry Pi 3B serial port, to achieve the purpose of using the serial port to send and receive data. Previously thought this serial port is the default to be formulated into a serial control

(decorated with @ post) The first route is very simple, that is, reading the index template (the template is html) and sending it to the client (browser), because the path is "/", that is, for example, the IP address of Raspberry Pi is 192.168.0.10. Use http: // 192.168.0.10: 8080 to access our "/" route (the default port of the bottle is 8080) Similarly, the second route path is "/cmd", that is, access ht

1. Effect display2. Hardware devicesIn a treasure bought a 4-bit common yin digital tube. 4 Number of common one cathode, altogether 12 pins. One of the 6,8,9,12 is a common-yin pin.　　Each number consists of A-g 7 diodes and a point DP. Because it is bought online without detailed device manuals, you can only test the pin and the digital diode on the corresponding relationship.　　You can see that the number 12th pin corresponds to the first digit of the common yin pin, the number 1th pin correspo

　　The GPIO pin has two modes board and BCM.1.GPIO output Control LED：　　Code:　　　　(1) Using board mode, GPIO.setmode(GPIO.BOARD) . Pin 35th is GPIO19 under BCM.(2) Set pin 35 to output mode,GPIO.setup(35,GPIO.OUT)(3) on the GPIO35 pin output high level, can also be Gpio.high2.GPIO interface for input signal：　　Circuit diagram　　When the switch is off, the GPIO23 is the high point level to obtain the input signal is ture.
