This I2C tutorial shows you how the I2C protocol works at the physical bit level discussing single master mode (a single controlling device) which is the most common use for I2C in a small system. I²C (pronounced I-squared-C) created by Philips Semiconductors and commonly written as 'I2C' stands for Inter-Integrated Circuit and allows communication of data between I2C devices over two wires. It sends information serially using one line for data (SDA) and one for clock (SCL).

A common way to do this is with a serial terminal program (hyperterminal, Arduino serial monitor, etc.). Asus Brings Its Tinker Board To North America Asus announced that its Tinker Board is now available in North America. Previously available only overseas, the Asus Tinker Board is a single-board computer powered by a 1.8GHz Rockchip RK3288 quad-core processor and 2GB of dual-channel LPDDR3. The 85.60 x 56 x 21mm device features 1Gb Ethernet, a Mali-T764 GPU with HD/UHD video playback support, H.264/H.265 decoding, 192kHz/24-bit audio support, four USB 2.0 ports, Bluetooth 4.0, and built-in 802.11b/g/n WiFi. Despite its credit card-sized package, the Asus Tinker Board packs as much power as many Chromebooks. Enterprising enthusiasts and hobbyists have made use of single-board computers for gaming emulators, robotics, car computers, HTPC media streaming, mini web browsers, file storage servers, cloud servers, home automation--the list goes on and on. All that power in such a tiny package means the possibilities to create personalized devices are endless.
STEM Role Models Posters — In 7 Additional Languages At the end of Nevertheless Season Two, we commissioned another four female illustrators from South America, Africa, the Middle East and China to produce a new set of posters. They were originally produced in English but we are delighted to say you can now download the complete set in 8 languages including French, German, Spanish, Italian, Portuguese Brazilian, French Canadian, Simplified Chinese and English. The women featured serve as amazing role models in their fields of science, technology, engineering, and mathematics (or STEM as it’s often referred to). You can listen to our episode on STEM Role Models here. We’d love you to download the posters and print them out for your school or workplace. By taking part, you’ll help raise awareness of their achievements, and hopefully inspire a new generation of girls and women in STEM.
Sockets de serrage sur le câble ruban It's a good idea to use sockets and header pins when working with ribbon cable. They make your projects more modular, portable, and able to be assembled and disassembled rapidly. You can get 16 stranded ribbon cable, sockets, and male header pins at Jameco: How-to: Bus Pirate v1, improved universal serial interface We use the Bus Pirate to interface a new chip without writing code or designing a PCB. Based on your feedback, and our experience using the original Bus Pirate to demonstrate various parts, we updated the design with new features and cheaper components. There’s also a firmware update for both Bus Pirate hardware versions, with bug fixes, and a PC AT keyboard decoder.
Chargeur Twitter Pet contrôlée A great project for busy pet owners. This Twitter-Controlled pet feeder automatically dispenses food in response to activity on your Twitter account. The project is controlled by an Arduino and uses the SEEED Ethernet shield to receive data from Twitter. I hacked this automatic Pet Feeder from Amazon to build this project, but you could easily modify your own motorized feeder to work.
