[PoBot] Débuter avec une carte Arduino

atoms&electrons Also check out the Apple //e Twitter Display for another take on this idea. I’ve partitioned my social networking life into two fairly distinct pieces. Facebook is for friends and family, and Twitter is for my technology hobbies. ArduinoBoardMega2560 Overview The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. arduinoscope - Oscilliscope and logic probe using arduino and processing I saw the wonderful arduino/processing scope, and thought of many improvements, including: logic analyzer mode that shows 1's and 0's clearly. pause frame save frame configurable pin-count use as many pins as will fit on screen (tested with 12 at 800x800, seems ok) use scope class in your own thing, easy to reuse, and setup any kind of GUI shows volts, based on scaling settings Arduinoscope is very much a DIY sort of tool. It makes it easy to set it up however is useful.

.: oomlout :.: Breadboard Based Arduino Compatible (BBAC) Micro-Controller While work continues full steam ahead at .:oomlout:. HQ last week we reached a point where all of our pre-existing projects were on hold. We were either waiting on packages to arrive or searching for the much more elusive delivery of inspiration.

Arduino « The Rantings of a Techno-Mage I bought an Arduino some time ago, but now I just received an ATMega168 from Daniel Jouiffe in Canada. He’s doing a trust scheme where he burns the boot loader onto an ATMega168, and then posts that and a 16MHz crystal to you, where ever you are. Then you pay him back however much you want. I just put into my Arduino NG board, and it works really nice. I’ve just doubled most specifications of my ATMega8. The forum post is here. Arduino Based Reflow Oven Controller – Testing & Progress No, this post is not about Megatron looking for energon cubes. We just love labeling all our tools and machines with characters from the show we heart when we were young. Alright, finally there’s some progress on the reflow oven controller.

A "Minimal" Arduino/XBee/Pachube Sensor Network One or two people have asked in online forums for code from my sensor network, and while I'm usually happy to share, it's full of a lot of extraneous stuff (RTCs, NTP, displays, thermocouples) that might not be of interest to everyone, but more importantly, that probably only obscures the fundamentals of XBee networking and communicating with Pachube. So with that in mind, I cut out the extraneous stuff, and just left the bare essentials: A remote sensor unit which transmits a single reading from a photocell once per minute to a base unit which connects to the internet and forwards the data on to Pachube. XBee configuration:

Open Accessory Development Kit The Accessory Development Kit (ADK) is a reference implementation for hardware manufacturers and hobbyists to use as a starting point for building accessories for Android. Each ADK release is provided with source code and hardware specifications to make the process of developing your own accessories easier. Creating new and alternative hardware based on the ADK is encouraged! Android accessories can be audio docking stations, exercise machines, personal medical testing devices, weather stations, or any other external hardware device that adds to the functionality of Android. Accessories use the Android Open Accessory (AOA) protocol to communicate with Android devices, over a USB cable or through a Bluetooth connection. If you are building an accessory that uses USB, make sure you understand how to implement the AOA protocol to establish communication between your accessory hardware and Android.

USB Host and Accessory Android supports a variety of USB peripherals and Android USB accessories (hardware that implements the Android accessory protocol) through two modes: USB accessory and USB host. In USB accessory mode, the external USB hardware act as the USB hosts. Examples of accessories might include robotics controllers; docking stations; diagnostic and musical equipment; kiosks; card readers; and much more. This gives Android-powered devices that do not have host capabilities the ability to interact with USB hardware. Android USB accessories must be designed to work with Android-powered devices and must adhere to the Android accessory communication protocol. In USB host mode, the Android-powered device acts as the host.

Adventures in Android ADK Development: Hardware At this point in my Android saga, I’ve gotten the Android SDK and Eclipse all running well enough to run a Hello World in the Android emulator. This is an important step, but I want more. I want it running on real hardware! In this case, a Nexus One phone. I installed a system update to bring the phone up to snuff, specifically to OS version 2.3.4 (Gingerbread). Petter’s Robot dreams » DIY Segway embedded by Embedded Video YouTube Direkt Why build a DIY Segway? The main reason that I wanted to build a DIY Segway was simply because I wanted to see if it was possible. I also liked the idea of building something that strongly interacts with humans. I will now describe how I built it.
