How to control DI.O devices with a Raspberry In this post, I will explain or describe how to control DI.O (from Chacon) with a Raspberry Pi and some cheap component. Price: less than 90$ DI.O devices are produced by Chacon and allow to manage 220V device via radio transmission (433Mhtz). Here we will replace the remote with our Raspberry Pi. Most of the info I get and I used to make this project has been found on this blog (in french). Thanks to IdleMan (y)
More 433Mhz RF Hacking I touched on the smoke detectors and door/window sensors I ordered last week: – here are a few more details. The smoke detectors were £5.75 each – (all now sold out, but more available on a separate listing from the same seller – The door/window sensors were £2.50 each – (shop link if/when the listing ends – The RF signals broadcast by both devices are not decoded by the RFXCom receiver/transceiver RFXtrx433. Safe Automated Mains Sockets What's this all about? This page describes how to turn mains powered appliances on and off under computer control without risking killing yourself. That last part is kind of important. Links for source code downloads Switch.cppWeb Interface More Detail
s Raspberry Pi Lesson 4. GPIO Setup One of the great things about the Raspberry Pi is that it has a GPIO connector to which you can attach external hardware. The GPIO connector actually has a number of different types of connection on them. There are: True GPIO (General Purpose Input Output) pins that you can use to turn LEDs on and off etc. I2C interface pins that allow you to connect hardware modules with just two control pins SPI interface with SPI devices, a similar concept to I2C but a different standard Serial Rx and Tx pins for communication with serial peripherals ESP8266 Serial WIFI Module - ITEAD Wiki Overview ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.
A Multi-Protocol Infrared Remote Library for the Arduino Note for Arduino 1.0 An updated version with 1.0 support is available on github. Installation instructions are at the bottom of that page. Let me know if you encounter any problems. Do you want to control your Arduino with an IR remote? Do you want to use your Arduino to control your stereo or other devices? Decoding 433MHz RF data from wireless switches [Update 2013-03-01] I have added more documentation on the codes these remotes use in a different post. I’m starting to move towards not only gathering information but also acting. My first project in this subject will be controlling some lights and the house heaters. So last week I visited the urban market of “Els Encants” in Barcelona and bought some very cheap wireless outlets. I bought two sets of three wall plugs, each set with it’s own remote.
Interface with Remote Power Sockets – Final Version « Rayshobby In previous blog posts, I’ve described two ways to use an Arduino to interface with an off-the-shelf remote power sockets / switches. The first method uses transistors to simulate button presses. It involves some soldering and hacking the remote control unit. The second method uses an oscilloscope to sniff the signal sent by the remote control, and then simulates the same signal using an RF transmitter. learn.adafruit Stepper motors fall somewhere in between a regular DC motor (Lesson 9) and a servo motor (Lesson 8]). They have the advantage that they can be positioned accurately, moved forward or backwards one 'step' at a time, but they can also rotate continuously. In this lesson you will learn how to control a stepper motor using your Raspberry Pi and the same L293D motor control chip that you used with the DC motor in Lesson 9.
