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

This is a creation in Article, where the information may have evolved or changed. This program achieves LED blink in Raspberry Pi with Go lang.//This is the implemented with Hard-coding and uses only main Function.package mainimport ("FMT" "OS" "Time") Func main () {//Initialize GPIO25 FMT .

FirstSome time ago, took a little time to do the number of children learning problems of the small programHomeDo a problem interface (topics are randomly generated every time, subtraction)To record a problem.Now the question is coming, how can we know at any time whether the homework is finished?It's too hard to refresh every time you open the title record page.So I made a Raspberry Pi + small

The official Raspberry Pi camera Module, capable of shooting 5 million megapixel images and recording 1080p video, uses the CSI interface on the Raspberry Pi board.Installing the CameraFirst make sure that the Raspberry Pi system

Recent information when found remote control boat is also very fun, and the community just have water, see others play also quite fun, and four axes, technical difficulty and cost are relatively low, so decided to do a remote control ship.Initial implementation of the following functions1. Dual remote control based on Wfly 6 A and Android phone2. Android phone remote control can be video, that can see the video camera3. Forward and backward left/right remote function4. GPS-based navigation5.

First, the previous figure: Accessories used: 1. Main Character: Raspberry Pi 2. secondary role: Infrared Detection 3. Miscellaneous: bread, DuPont wire, buzzer, led, resistor The infrared detection has three pins. The power supply at both ends and the signal output in the middle directly connect the signal to a gpio of

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

Raspberry Pi advanced GPIO library, wiringpi2 for python Use note (3) GPIO operations, gpiowiringpi2 The core function of the GPIO library is to operate GPIO. GPIO is the "general input/output" interface, such as lighting up an LED or relay, or using iic spi 1-wire and other protocols, reading and writing data are all useful for GPIO. It can be said that without

Gpio Library core function, of course, is the operation of Gpio, Gpio is the "general input/Output" interface, such as lighting a LED, relays, or through the IIC SPI 1-wire and other protocols, read, write data, this is the use of Gpio, can say no gpio, Raspberry Pi can only be used as a small computer, with a gpio, it is upgraded to a controller.
