raspberry pi gpio setup

After buying the Raspberry Pi, what can I do with it? There are a few ideas to share with the beginner's teaching film, which is well worth a visit. Http://www.youtube.com/user/RaspberryPiBeginners 1.Plug in the expansion card, DIY or teaching.The main usage, of course, is to plug in a GPIO card, put on a noodle board, pull some electrical circuit, control what t

I see this software development stalled and sad, as if they didn't have more contributors to the larger community (though many people still use it).CraftbeerpiThen I stumbled across a Python-written craftbeerpi, which has an active contributor-supported development community. The original author (and current maintainer), Manuel Fritsch, has done a good job of contributing and handling feedback issues. It took me a little time to clone this ware

The answer is yes. There are 26 pins on the Raspberry Pi Board, these gpio (general purpose I/O) including SPI, I²c, serial UART, 3V3 and 5V power supply. Domestic forum There is an article "RASPBMC Setting Infrared receiver" describes how to install the RASPBMC operating system for Raspberry

, please plug in the brush board, using the accompanying checkchipversion. WIN7/8 PL2303 users can directly plug in the brush board, the system will automatically download the driver (of course, to network). However, after plugging in the machine board, you will see the normal running COM device in Device Manager before you can proceed to the next step.Then make some settings:Set the baud rate of the brush board to 115200 (because the Raspberry

. Click Add event Select a title for your time. We recommend that you do not add any spaces to the event name. I am using "DoorAlert" You need to add at least one tracker. This is basically a variable used in push notifications. I name it "message" Finally, enter the message content you want to push. My Python code sends the variable {message} to the Instapush service. Therefore, I suggest you only add {message} to the Message field. Click Add event Click the Basic Info tab and write down th

binds a click event to all buttons, and line 3 calls the post method of jquery to call this. id (the id of the clicked button) is sent to the path "/cmd". At this time, the second route of the python code takes effect and receives the id of the clicked button on the webpage, and printed the "pressed Button: XXX" Of course, you can write a few if statements here to make some actual control as needed. Well, for example, you can call wiringpi2 for python to control the
