For students to do a smart home tutorial: The use of Raspberry Pi as a server, we through the method of accessing the server, control the high and low level of the I/O port of the Raspberry Pi, I/O port connected on the relay (to achieve low voltage control high voltage), relay you can be arbitrarily connected to the h

Recently want to use Raspberry Pi control model of the ESC, so studied the next PWM, seemingly control the ESC is troublesome, because the ESC needs to send a few specific signals to start, and then to enter the control mode, today first understand PWM, slowly toss. The following program pro-test is available, I use the Raspberry

problem, the following task is simple. For pythoner, the things mentioned below are not called things!Pai_^ Below is a simple list: A song is captured from sogou MP3. You only need to enter the name of the song and search automatically. Then, the URL of the song is returned. The Web management interface is implemented using web. py to display the list of songs and songs being played in real time. The database uses sqlite3 to save the song information entered by the user for late

Tags: Raspberry Pi wiringpi Zookeeper 1. Void pinmode (INT pin, int mode ); This function sets the Input and Output Modes of the pin and the input and output modes of PWM. InWiringpi onlyPin 1 (bcm_gpio 18) supports PWM output. 2. Void digitalwrite (INT pin, int value ); This function is used to set the level of the pin. When we write high or low (1 or 0), the mode of the pin must be the output mode.

Installing ROS Indigo on the Raspberry PiDescription:this instruction covers the installation of ROS Indigo on the original Raspberry Pi with Raspbian.Keywords:raspberry Pi, Setup, IndigoContents1 IntroductionThis tutorial explains how to install ROS Indigo from source on th

We have explained in detail the Raspberry Pi control ultrasonic module ranging (http://www.cnblogs.com/yuemo/p/8888342.html) and ultrasonic control buzzer module audible (http://www.cnblogs.com/ yuemo/p/8906111.html).Today we'll see how to apply all two modules and make an anti-theft device.First look at the connection of each pin (requires seven mother-to-female DuPont line):Ultrasonic module:1.VCC: Connec

Color control for RGB LEDs with Raspberry Pi RGBColor Modeis a color standard for industry. is through theRed (R),Green (G),Blue (B)Three ColorsChanneland they overlap each other to get a variety of colors, RGB is the representativeRed,Green,Bluethree channels of color. This standard almost contains all the colors that human vision can perceive, and is now the most widely usedColor System one of them. Th

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data is connected to the Gpio (I'm picking up the B

the digital tube. The correspondence depends on the order in which you send the data when you wire and write the code. DS is a serial input pin, so-called serial is to make the data on a signal line in order to transmit one by one, like a string of candied fruit. This pin we received from the Raspberry Pi at any one of the Gpio ports (output mode). The
