Top 10 Things to Connect to Your Raspberry Pi

Top 10 Things to Connect to Your Raspberry Pi
During my time with the Pi I’ve experimented with various devices and sensors. Here is my Top 10 list of devices to connect to the Raspberry Pi. In most cases they are very cheap and easy to interface and are great building blocks for more complicated future projects. I’ve included links to more detailed posts where I can and many of these include example Python scripts to help you get going. From robot cars to security systems there are plenty of ways of combining these mini-projects into some amazing creations! Ultrasonic Module Ultrasonic Sensor Ultrasonic transducer modules are an easy way to add distance measuring capability to your Pi. Take a look at my “Ultrasonic Distance Measurement Using Python” posts to see how you can connect one to the GPIO header and read it via a simple Python script. PIR Movement Sensor PIR Module Simple “Passive Infra-Red” sensors allow you to detect movement. An example python script can be found on the “Cheap PIR Sensors and the Raspberry Pi” page.

Build an LED Indicator with a Raspberry Pi (for Email, Weather, or Anything) The Raspberry Pi makes a nice compact platform to attach an indicator light to for all sorts of projects—weather notification, new emails, etc. Read on as we show you how to hook up an LED module to your Pi and set up some basic notifications. Why Do I Want to Do This? Because it’s fun. Unlike many of our tutorials where we include a little blurb at the top outlining exactly what benefit you’ll derive from the project, the blurb is pretty short in this case because the benefit is simply having fun. The Raspberry Pi is a perfect device to play around with, experiment with electronics, and learn some programming. What Do I Need? To follow along with out tutorial you’ll need a few things. In addition to having a functional Pi unit with Raspbian installed on it you’ll need the following things: Note: The clear/frosted Pi case is entirely optional but if you’re currently using an opaque case then your LED indicator will be hidden inside.

Test du mini clavier sans-fil RT-MWK0 iclever Rii 2.4GHz Pour ceux qui sont à la recherche d'un mini clavier sans-fil pour utiliser une tablette, un smartphone, Google TV, PS3 ou son Raspberry Pi préféré, voici le mini clavier sans-fil RT-MWK0 iclever Rii. Ce mini clavier dispose d'un clavier AZERTY simple (67 touches) relativement ergonomique, d'un touchPad (agrémenté d'un pavé directionnel et de 2 touches "clic droit"/"clic gauche") et d'un pointeur laser. Il existe deux versions, l'une Bluetooth (parfaite pour les appareils Android/iPad), l'autre Wireless 2.4GHz (celle que j'ai choisie). La différence entre les deux versions ne réside que dans le protocole de connexion. Pour le reste, les caractéristiques sont les mêmes : Le packaging et la prise en main J'ai souvent lu des compliments sur le conditionnement Amazon et je n'ai pas été déçu : le carton de protection est solide. L’appareil est assez simple : à gauche le clavier AZERTY et à droite et le pavé tactile accompagné d’un pavé directionnel. Utilisation sur Raspberry Pi et média center

Voyant pour indication de la température Hello, aujourd'hui j'ai décide de me pencher sur un des avantage de notre petit raspberry pi qui est la possibilité d'utilisé des broches GPIO, pour contrôler de l’électronique et faire de la domotique. Pour commencer petit j'ai récupérer deux led une rouge et une vert, mon objectif est que la LED verte informe d'une bonne température exemple inférieur à 40°C et la rouge pas conséquent pour les température supérieur. Dans un premier je me suis informer sur comment utiliser ces fameuse broche, je suis donc tombé une schématisation de ces broche (ce schéma va vous servir longtemps :D) : Ensuite grâce a ce croquis j'ai fait un schéma de mes LED : Une fois le câblage fait il faut passer a la partie programmation et la un outils maintenant indispensable est à installer c'est une librairie qui va permet d'actionner directement les entrée sortie gpio, je vous laisse suivre le tuto du créateur de cette bibliothèque, c'est simple et rapide (lien). #!

8 great Raspberry Pi projects created by kids What do you get when you combine the Raspberry Pi with some inspirational young inventors? Terrific Raspberry Pi project designs, that's what. Fourteen groups of teams from schools, universities and businesses gathered in late March at PA Consulting Group's Cambridge Technology Centre for the awards ceremony of the PA and Raspberry Pi-making competition. The young programmers presented their inventions to a hand-picked judging panel after being given three months to work on their designs, a £25 Raspberry Pi and up to £50 of additional hardware and software. The idea was that the inventions should be beneficial to others – perhaps enabling better healthcare delivery, promoting information or benefiting the environment. The competition was launched in response to a fall in programming skills and was aimed at increasing the numbers of skilled coders, developers and engineers. So without further ado, let's check out some of the projects put together by the teams: 1. This school loves running.

Raspberry Pi without keyboard, mouse nor screen. &emdash; Edmundo Fuentes I’ve been wanting to mess around with a Raspberry Pi ever since the day it was announced. The thing is, right now I’m studying abroad, so buying a dedicated set of peripherals (keyboard, mouse, screen, etc..) was not an option. However, it occurred to me that I could use my own MacBook as my RPi’s HMI. After checking some sources and asking around on the IRC channel, I found out that it could be done, so without hesitating I ordered myself one. I’ve written this little guide to help you configure your RPi with a lightweight VNC server to get you started in case you lack the hardware peripherals. 0. I’m not going to get into much detail here since it’s been widely discussed on the web. 1. This is actually the “hardest” step since it’s pretty much guessing and a little bit of luck. I’m using my MacBook’s built in “Internet Sharing” feature, I’m sharing my internet connection from WiFi to my ethernet port, to which the RPi is directly connected. 2. > ssh pi@192.168.2.X Congrats! 3. 4. #!

Déclencher un ventilateur avec seuil de temperature sur raspberry pi via python et gpio | Syris.fr En faisant mes essais OpenCV sur mon raspberry overclocké, je me suis aperçu qu’il était indispensable de refroidir celui-ci. Mon habituel dissipateur ne suffisant pas, j’ai donc intégré un mini ventilateur en 5v piloté via un transistor NPN (afin de ne pas bousiller mes GPIOs) Le faire tourner tout le temps n’ayant pas d’intérêt, j’ai voulu utiliser la fameuse commande : Et vu que j’ai un peu galèré pour récupérer cette info et la traiter correctement sous python, je partage la chose au cas ou vous en auriez besoin ! Le schéma (très simple) : La led (et sa résistance) n’est la que pour l’esthétique.EDIT : Finalement, j’ai utilisé un TIP121 à la place du BC337 (pour supporter un ventilo plus puissant) Et le programme sous python qui va bien : Publié dans Blog, Raspberry

How to Tether Your Raspberry Pi with your iPhone 5 | DaveConroy.com Posted by dconroy on Jul 3, 2013 in How To's | 26 comments | 51,826 views If you have been reading my blog lately you know that I have done a lot of projects involving Raspberry Pi‘s, the $35 dollar credit card sized Linux computer. Because of its small size, I recently started of thinking of projects that would allow me to be mobile with the Pi. That led me to this post. There are plenty of resources online about tethering the iPhone 5 with the graphical interface, but I wanted to be able ‘hotswap’ my Raspberry Pi’s Internet connection without command line, and without the graphical interface. Plug and play, essentially. I was able to get this working last night using Raspian (a free operating system based on Debian optimized for the Raspberry Pi hardware) and a few scripts. Prerequisites Make sure your iPhone is disconnected and proceed to install the following iPhone and file system utilities. If you have a standard installation, you should see two interfaces, eth0 and lo. Command Line #!

dangardner/pylcdsysinfo SMS Gateway : une passerelle SMS à la maison Si vous avez votre serveur domotique en place et qu’une alerte doit vous être remontée il existe plusieurs manières de le faire : SMS, Pushme.to, push via l’application Smartphone de votre serveur domotique… Ces solutions marchent très bien mais ont un point faible: elles nécessitent une connexion internet. Les SMS par exemple sont générés par votre box domotique puis sont envoyés en HTTP sur internet au serveur central de votre solution domotique. Là ils sont envoyés au format SMS sur le réseau GSM via une passerelle. Avec l’arrivée des forfaits à tarifs réduits (merci Free! La passerelle SMS pour être compatible avec le maximum de solutions domotiques (on n’est jamais à l’abri d’en changer ou d’employer plusieurs à la maison) doit pouvoir discuter de manière simple et standardisée. La passerelle SMS doit pouvoir avoir une alimentation secourue afin de faire face à des coupures électriques. La passerelle SMS doit pouvoir être simple d’utilisation et de paramétrage. Tout est possible!
