1: Getting Started with Raspberry Pi GPIO and Python 1: Getting Started with Raspberry Pi GPIO and Python Details Category: Raspberry Pi Last Updated on Friday, 06 March 2015 12:37 1. Overview Tutorial - How to give your Raspberry Pi a Static IP Address Tutorial - How to Give your Raspberry Pi a Static IP Address To log in to your Raspberry Pi remotely, you'll need the IP of the Raspberry Pi – this is basically like your house address and tells the host computer where to look for it on the network. By default, the Raspberry Pi will be given an IP automatically by the router (called Dynamic IP and denoted by DHCP) when you connect to a network. However, this can change whenever you remove the Pi from the network e.g. turn it off.
Raspberry Pi Camera - MyLabWiki Usage Currently, there are are two options for getting video out of the Raspberry Pi camera: The raspivid application The V4L2 interface (beta) The v4l2 interface can be useful for applications that only have that input options. USB RFID + Python + Pub-Sub (MQTT) Now that we've got an RFID reader and pub-sub client working separately, it's time to combine the two functions to achieve the end result. The following code does exactly that. Here's how it works: - When the script starts the 'open_reader()' function is called which opens the card reader or exits the script upon failure. - Displays card information - Connects to the MQTT server of quits upon failure. - Begins the main loop - The listen_card(card, interval) function starts a loop that checks a card is sitting on the reader. Once a card is found, the card ID, time and date, and action (placed or removed) is published and the function returns. - The listen_remove(card, interval, card_id) function works the same as listen_card, however, the data is publish when the card is removed. - The loop repeats.
What is XBian? XBian is a small, fast and lightweight media center distribution for the Raspberry Pi, CuBox-i, Hummingboard and many more devices to come. It is based on a minimal Debian and therefore offers much of the same freedom as Debian offers. Our slogan is “XBian, the bleeding edge” as our main focus is delivering the fastest Kodi solution for various small form factor computers. Small footprint and easily customizable Basic Electronics There are two types of electrical signals , those being alternating current (AC), and direct current (DC). With alternating current, the direction electricity flows throughout the circuit is constantly reversing. You may even say that it is alternating direction. The rate of reversal is measured in Hertz, which is the number of reversals per second. So, when they say that the US power supply is 60 Hz, what they mean is that it is reversing 120 times per second (twice per cycle). With Direct Current, electricity flows in one direction between power and ground.
How to Change Your Raspberry Pi (or Other Linux Device’s) Hostname The default hostname for the Raspberry Pi is, creatively enough, “raspberrypi“. What if you want a different hostname or you want to avoid hostname conflicts on your local network? Read on as we show you how to quickly change the hostname of a Linux-based device. Raspberry Pi camera board – Gstreamer So, my Raspberry Pi camera board has arrived and I have started playing with it. My first impressions were tiny, super cheap camera. Its low light capabilities are not great but I can live with that. The important bit is the quality, full 1080p at 25 frames per second (UK). That on its own is pritty awesome. Documentation - RFID/NFC 13.56 MHz shield for Raspberry Pi tutorial Tutorial Index Introduction RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to identify objects in a contactless way; it is also called proximity identification. There are 2 elements in RFID communications: the RFID module (or reader/writer device) and an RFID card (or tag). The RFID module acts as the master and the card acts as the slave; this means the module queries the card and sends instructions to it. In a normal RFID communication, the RFID module is fixed and the user takes his card near it when he needs to start the interaction.
Installing OpenELEC on Raspberry Pi This is for users with a Linux computer. Installing OpenELEC for Raspberry Pi from a Linux computer is a very simple process and whether you're new to Linux or a hardened *NIX user, you shouldn't have any problems. A computer (your normal PC) A Raspberry Pi Media to install to (SD card) How to control arduino board using an android phone and a bluetooth module The circuit is as simple as it gets so you probably already have most of them. You will need: - arduino board - bluetooth serial module (I used a btm222 module on a breakout board with an inbuilt regulator ) - an LED - resistor (100ohm) - wires - breadboard The only problematic part here is the bluetooth module. There are different modules all over the internet so be sure you check the pinout in the datasheet of the one you get as it can differ. Also notice that there are two general classes of bluetooth modules: Class 1 has range of about 100 meter (300 feet) Class 2 has range of about 10meter (30 feet) In case you're wondering they are entirely compatible and you can only get 100 meter range if both of the devices (ie the mobile and the serial module) are class one. If one of it is class 1 the maximum range is lower.
