Decoding and sending 433MHz RF codes with Arduino and rc-switch In this tutorial I’ll show you how to use an Arduino to decode signals from RF remotes, and re-send them to remotely control some mains switches and a garage door. RF transmitter and receiver modules connected to the Arduino using a solderless breadboard and jumpers Arduino – I’m using an Arduino Uno Rev3.433.92Mhz RF Transmitter and Receiver Pair – I got mine from eBay for the ridiculously cheap price of $1.45: Transmitter Model No: MX-FS-03V (marked XD-FST) Receiver Model No: MX-05V (marked XD-RF-5V) They work just fine – the main problem is that there is no datasheet or documentation available. Some basic specs are available on but that’s about it. Similar modules should also be available at your local electronics shop e.g.

Arduino + Servo + openCV Tutorial [#openFrameworks] by Joshua Noble One of the my favorite things about has always been the small tags one can find beneath the name of an application indicating among other things, the technology used to create it. That little nod to the process and to all the work that went into creating the libraries and techniques that an artist or designer uses helps not only contextualize the work but it also helps give recognition to everyone who has contributed their time and expertise to building tools for creative expression in code. Figuring that some of the readers might be interested in learning a little more about these frameworks I’ve put together a quick walk-through of how to connect up two of those tools that one so often sees attached to the names of the projects profiled here: openFrameworks and Arduino. Arduino For this tutorial you’ll need a few things: 1 x Arduino-compatible device 1 x Trossen Servokit 1 x USB cable 1 x Breadboard and wires to connect the Servos to the Arduino

[SMS] Sony Ericsson PDU Summary For nothing have I had more requests than this piece of code. It’s use is obvious; forcing a turned on Sony Ericsson that supports a real serial interface to send a sms, receive, read, call etc. The hardest part in this is sending an SMS through real serial with f.e. an Arduino using this Sony Ericsson cellphone. Arduino Examples Arduino Examples These examples are designed to demonstrate how to use our modules with the Arduino. The Arduino's hardware serial port is not used to connect to our modules, which keeps it available to the USB port. That allows downloading new programs without having to continually disconnect/reconnect things. Most of these examples use the LCD03 display module to show the results, but it is also possible to display the results on the PC, as demonstrated in the CMPS03 example. All the modules which use the I2C bus have 1k8 pull-up resistors to 5v.

Arduino ATmega328 Hardcore Arduino ATmega328 - Hardcore Ok, you've completed your prototype using an Arduino Uno board, perhaps using a shield or a breadboard for any additional components, but now you want to finalise your design and construct it using your own pcb. Well, that is fairly straightforward, as we have made a complete kit of essential parts available for the ATMega328 micro (click here). The kit includes the following items (depending on which bootloader chip 16MHz or 8MHz)

» Search Results » oregon » JeeLabs In yesterday’s post, I used the OOK Scope to find the distinctive pulse pattern emitted by a specific sensor to be able to write a decoder for it. Keep in mind that this is a bit like looking for a needle in a haystack: there are often over a million pulses coming in within just minutes. That’s why I had to compare the “sensor-off” baseline with the “sensor-on” pattern. Monochrome OLED Breakouts This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! The driver chip, SSD1306 can communicate in multiple ways including I2C, SPI and 8-bit parallel.

GSM Alarm - PROJECTS * SMS Alarm This Software uses Arduino connected to a mobile phone(SIEMENS C75) and it sends a SMS when a certain amount of light is off (LDR) and it sends another (SMS) after light values are restored.

I2C Tutorial Using the I2C Bus Judging from my emails, it is quite clear that the I2C bus can be very confusing for the newcomer. I have lots of examples on using the I2C bus on the website, but many of these are using high level controllers and do not show the detail of what is actually happening on the bus. This short article therefore tries to de-mystify the I2C bus, I hope it doesn't have the opposite effect!

Development Team/Arduino There are different options to connect your arduino board to Sugar (trough sugar-capable activities) Squeak Thanks to the great work found on Gira We can download an squeak project and install it on our Sugar. This script can help in the process.
