W00t! My new and only arduino just arrived!
Ordered it from eBay(HK, cough cough) instead of buying it here in Brazil. Obvious choice because it would cost me 62.6 USD instead of the 15 I payed.
I bought the Duemilanove, discovered later I should have bought the UNO, which has the ATmega8U2 instead of the FTDI to communicate via USB. This is better because the ATmega8U2 is programmable, so you could make it act as any USB device instead of just a virtual com.
Getting started is ridiculous, in ubuntu at least. Just download the arduino software available at arduino.cc, extract and run.
Select your board in Tools, and other minor configurations, paste the LED Tutorial(also available at the official site) onto the sketch and upload. There! Your first arduino code running!(Note that the 2009 already comes with a LED connected to the pin 13, no need to connect another)
The interesting thing is, the USB-TTL used to program the arduino can be used to communicate with your code that’s running inside the arduino! When using this feature, the pins 0 and 1 (digital), which are named RX and TX respectively, are/can be used to connect a serial ttl device directly to the computer.
Why is this so nice? I bought a bluetooth TTL module which I plan to connect to the arduino and make it talk to android!
With the launch of the ADK(Open Accessory Development Kit for android, which is basically an arduino with various sensors) you can now connect it via usb on the android an do all sort of stuff.
With a non-official ADK arduino, you must make use of the USB-Host shield and use the new lib.
First, ADK should be able to be host OR client, depending on the power source. Don’t know if the USB-Host shield supports this and/or the android device must be able to provide power via the usb interface. I should look into it… someday.
Second, the arduino UNO allows for USB device ’emulation’. Is the USB-Host shield really needed or could the ATmega8U2 be programmed to act as an ADK device/proxy?
a new hope a new turn. I should be posting stuff about the arduino and what I’m trying to do with it in the not that near future.
Some other posts are coming along slowly, when I have the opportunity to write. Must stop procrastinating!
