I just got my Arduino last week, and although this is my first intro into electronics so I was very excited to get it and try out new things.
Why i liked Arduino a LOT:
– it lets me code in java (using the Processing IDE) and deploy my IO code directly onto the device through an USB cable
– You can program it to handle various kinds of serial devices, and has out-of-the box support and great tutorials for some of them right on http://www.arduino.cc
– You have 6 analog pins which lets you play around with analog stuff like sensors
– For beginners: it quickly lets you play around with leds 🙂 *blinky*
– A lot of support for various hardware and a great forum to figure out how to connect your devices or interface with some requiring additional circuitry
What i miss:
– You cannot make Arduino become an USB host for various technical reasons, excepting a limited range of hardware which can be converted to serial, so some of my wild dreams where killed right here
– With the standard Arduino (Duemillanove) you cannot communicate to more then one serial device at a time (Only one RX pin) so you can’t really connect a Keyboard and a midi IN/OUT interface and so forth without additional electronics (like switching devices on a PIN so you can separate interrupts)
It would be great to have something like this built onto the motherboard by default. My example would be if one wants to create a small usable midi controller (THRU) he will need IN and OUT so it can be added to the midi chain of synths and controllers.

So here are my Arduinos:
1. original bought from http://www.robotop.ro
2. My etched version
3. The famous breadboard version
What I am trying to accomplish now is to interface two low cost arduinos based on the Atmega8 chip to multiply the IO operations one board can handle using just a few of the digital pins. My ultimate goal is to build a nice sequencer with MIDI In/Out/Thru using Arduino.
