MakersWorkbenchDue

Here's a detailed overview of the Arduino Due from The Makers Workbench:

When I first got my Due in the mail I searched the web for a simple overview to help me better understand what new features Arduino is bringing to the table with the new development board. After finding next to nothing I decided to write my own general overview post in hopes that it would help out someone in a situation similar to mine. The Arduino Due is the first ARM-based development board from Arduino and features a powerful 32bit CortexM3 microcontroller. The board is fully programmable through the familiar Arduino IDE. The processing power is significantly increased over a traditional 8bit Arduino board and the coding language was kept very similar to what we are familiar with, making the transition to the new board very easy for most.

The Arduino Due shares a similar form factor to that of an Arduino Mega with the due having a few more pins, and two micro-USB ports instead of one. The Due sports 54 digital I/O pins of which 12 are PWM enabled, 12 Analog inputs, 4 UART's, a USB-OTG capable connection, 2 DACs, 2 TWI, a JTAG header and SPI connector. An 84MHz clock fuels the CortexM3 engine and the boards operating voltage is 3.3v unlike the previous Uno, Leonardo, and Mega which all run on 5v. The Due is able to handle input voltages from 6-20V, but the recommended input voltage is between 7 and 12 volts. The total DC Current output on all I/O pins is 130mA while the current for the 3.3v and 5v pins is limited to 800mA. Because of the Atmel SAM3X8E's 3.3v limit, existing Arduino shields that utilize 5v won't work properly on the Due. Shields that utilize Arduino's official R3 layout will work out of the box however.

It is important to note that using a shield that presents an input voltage greater than 3.3v to any of the I/O pins will damage that pin and could possibly (most likely) kill your Due all together. If you are unsure about a shield, I recommend that you fully read the shields data sheet, website documentation or contact the shields manufacturer before attempting to use it on your Due. Users have 512KB of flash memory to store their code in as well as two banks of SRAM totaling 96KB (Split into 64KB and 32KB). Compiling code for the Due is handled in the latest version of the Arduino IDE : Version 1.5, which will replace Arduino 1.0.1 after the testing phase completes.

But as it's rated for 400VDC, it's probably OK on 120VAC.

Fair enough. It must be frustrating.

It is not hard to make your own if you have a soldering iron. I made one that works pretty well. If you are interested, go to the libraries in my footer, look at the midi library and in the main library header file...

Re: Interfacing With The HDPM01 Barometer

Since the sensor board doesn't seem to have pull-up resistors for the I2C-bus, can you try 4k7 pull-up resistors from SDA and SCL to 3.3V ?
That would perhaps remove the false hit for 0x77.

Thanks for the photo, but the photo at deal-extreme is better....

MakerLab reviews the Arduino Starter Kit

Posted: 22 Jan 2013 03:45 AM PST

When we released the Arduino Kit, we knew that we are equiping the closet-wannabe-makers to start planning for world domination. Now it has the stamp of approval from MakerLab too!

Make Noise With The New Arduino Kit is a project by Alessandro Contini (@CNTLSN) and Alberto Massa (@nkint)

The above video explores the basic components of the kit and things that a new-maker would want to start with, including a light controlled theramin, and by theramin, I really mean exploring every possibe way to make impressive noises from one simple experiment.

Sounds fun? Do write to us, what you made out of your starter kit. We may feature you next

When I connect it the same way without the wifi shield it works fine... any ideas?

Re: Is it possible ?????!!!!

Posted: 23 Jan 2013 12:10 AM PST

Basically yes this is possible with a Uno. Depending on your skill level you can either build the extra stuff yourself or buy shields. The problem with shields is that you probbly will not find what you want exactly.
The 14 inputs can be put into two s...

eLeCTRONiC WeAraBLes Meeting WrapUp #WearableWednesday

Posted: 23 Jan 2013 12:00 AM PST

CrashspaceWearables01

Some wrap-up notes from a wearable electronics event and unconference held at Crash Space in combination with the LA Robotics Club!

We organized and hosted the LA Robotics Club this past Saturday Jan 19th for a Wearable Electronics Meetup. They'd been expressing interest in wearable electronics for quite awhile and it was a good excuse to open the space on beautiful Saturday afternoon.

We started will minimal expectations of an informal meet and greet, but around 70 people came. We had nearly 100 rsvps from different sources leading into the week of the event. free events are hard. arguably more work because you never know how many people will show up. The last thing I wanted to do was rent a room and not fill it… So, we went for it. we packed 'em in tighter and brighter!….

Given the amount of folks that were planning to attending and our limited space, I went for an unconference like format. It went quite well with minimal upfront work. My aim was to most quickly get everyone in BOF sessions where the space would be less of a constraint.

We started with name tags and small talk until the room got full
Then we briefly when around and everyone shared what they hoped to gain. I created a bit of a session board and noted who might be an expert in fashioningTech or robots.

We then allowed anyone to share something with the complete group. This satisfied the need for those that came with a product of self promotion to get traction. This included projects, problems, techniques, questions, or ideas….
