Turn your old cellphone into a smartwatch Turn your old cellphone into a smartwatch Arduino Team — July 20th, 2016 Do you have an old cellphone lying around somewhere? Don’t know what to do with it? Time to blow off that dust and convert the ‘dumb’ device into a smartwatch! DFUProgramming8U2 The ATmega16U2 chip on your Arduino board acts as a bridge between the computer's USB port and the main processor's serial port. Previous versions of the Uno and Mega2560 had an Atmega8U2. It runs software called firmware (so named because you couldn't change it once it had been programmed in the chip) that can be updated through a special USB protocol called DFU (Device Firmware Update).
Lifelong Kindergarten Group - Scratch Wiki The logo of the Lifelong Kindergarten Group. The Lifelong Kindergarten Group (LLK) is a group within the MIT Media Lab designed to "expand the range of what people can design, create, and learn". Some of the LLK's most well-known projects include Computer Clubhouses and Scratch. Mission Staff How To Unlock Netflix Hidden Categories - The Bro Talk You need to login in order to like this post: click here Do you ever feel Netflix has limited categories to offer you? Many of us spend hours browsing through all the titles displayed just to end up not watching anything. Well, the truth is that Netflix only shows you what they think you might want to watch. This is all based on an algorithm that uses what you have previously or regularly watch. But of course, there are ways around this to fully unlock all the categories.
create.arduino Overview The purpose of this project is to control and monitor a swimming pool using temperature sensors, relays and Microsoft Azure. The inspiration for this project is the need to remotely operate and monitor our kids swimming pool, which is an Intex 15' x 48" round pool. The pool holds approx. 5000 gallons of water. Arduino to Pure Data Arduino can output Serial data ( analog data ) from sensors connected to the arduino board. 1. Connect 5Volts to the Breadboard 2. Put a 1M Ohm resistor that leads the 5v to the channel where the light sensor will be.
Creating Computer Games with MaKey MaKey and Scratch Last week, I took advantage of two newer additions to my library district's programming supplies to offer a school-age STEAM maker program. I had sent to my branch one of our mobile computer labs--8 laptops, plus an instructor laptop, so those of us without dedicated program computer lab space can offer computer programs--and a kit of MaKey MaKeys, and a group of 9-12 year olds and I set to creating our own computer games with the added excitement of using the MaKeys to play them. Here's what we did. Part I: MaKey MaKeys To get things started, I introduced how circuits work; completing a circuit is key to getting the MaKeys to function properly, so the introduction seemed apt. From there, kids opened their MaKey MaKey kits and we started to attach the alligator clips to the board.
Developing for Developers – Tools, techniques, and theory for measuring and improving the power and performance of developers and their code Hey all – I apologize for the (extremely) long period of no updates, I’ve been prioritizing other things. I’ve been accepted this Fall to begin my Ph.D. at University of California, Berkeley. Since I won’t be at Microsoft any longer, I’ve started a new blog with a new focus and more regular updates called Papers… We’re entering an era where CPU clock speeds will soon cease to scale upwards and instead CPU manufacturers are planning to put more and more independent cores on a chip. Intel plans to release an 80-core chip within 5 years.
Keep Sharing Arduino & Genuino community pics and Win! Keep Sharing Arduino & Genuino community pics and Win! Zoe Romano — April 5th, 2016 April 2nd was a great day. We spent it celebrating Arduino and Genuino Day in more than 330 local communities and we had lots of fun! Our social channels were full of mentions from pics and messages about the events and all the activities you organized or took part to worldwide.
Easy Serial on the ATtiny Introduction The Atmel tinyAVR MCU's are great little chips for projects but can prove difficult to debug. Some ATtiny chips do not have direct support for hardware based serial and therefore the Serial object is unavailable in your code, however, it is easy to add a SoftwareSerial object and view output in the Arduino IDE. The code in this article uses an ATtiny85 with an FTDI Serial TTL-232 USB Cable to send or receive information. Scratch - Developers Where can I learn more about Scratch? Scratch is a free programming language and online community where young people can create their own interactive stories, games, and animations. Scratch is a project of the Lifelong Kindergarten Group at the MIT Media Lab. You can learn more about Scratch here. Are there rules to using this code in my application? You may use this code in accordance with the license which governs each project.
Adventures in /usr/bin and the likes - Dormammu's Blog I just love Linux! For me it makes interacting with your computer fun and educational. I think if someone needs to learn about the core principles underlying an operating system and hardware, Linux is a great place to start. As we all know interacting with Linux is achieved mostly through programs (commands). One of the things which differentiates Linux and the *nix based systems is the command line and the concept of pipes.
Arduino All-In-One Remote Infrared light has been used quite a lot for many different applications in many fields, one of them is communication, specifically between remotes and domestic devices, what allows us to control them without leaving the comfort of our sofa. The process of communication between an emitter (the remote) and a receiver (the device) starts when the user presses any button of the remote, this device has an oscillator and a preconfigured chip that allow the signal to adopt a square waveform with a frequency of 39kHz, depending on the button pressed, the chip will use a determined signal code. This signal travels through the circuit until it reaches the infrared LED, which transforms it into a series of pulses of invisible light (~940nm). If any sensor it's in it's range those pulses will be transformed into a quadratic wave that will indicate what to do according to the programming of the device.
