Yea, you are completely right, you will not need OSC, on puredata, but if you want to use it with another platforms/software you will need to use a different approach. One its Implement it with puredata as the middle man, translating the arduino data into OSC compliant data. Another is implementing some kind of networking on the arduino, either Wireless or wired. To work with the ipad, or iphone, you would need to implement a wireless (as WiFi) netwok adapter. Also, people should remember that OSC is mostly a network driven protocol contrary to MIDI that is a serial communication wired protocol, with fixed messages (although it is possible to send midi messages over network :D)

Just a clarification of my previous idea, when suggesting OSC;
Yes, pduino makes OSC redundant
Its not redundant if you wanna do stuff that work with a protocol instead of being Software-dependent =P It's just a harder way to go.. You build a foot controller and communicate with pduino, next day you wanna control an iphone... next day you'd like to send messages to your ipad or whatever, and so forth.. having standards helps if you need cross-working-stuff... if not: pduino will do just fine :) Of course you can allways try to read the arduino values from any plataform, but that's assuming a "different standard" :)

it says 5 samples per second. that latency would be unbearable...

Hi, and thanks for your answers. Yes, pduino makes OSC redundant, and a range of values from 0 to 1023 should be enough for most effects, but anyway, in case a wider range is needed, I think the following can be a quite simple solution : http://interface.khm.de/index.php/lab/experiments/connect-a-ltc2400-high-pre... This converts the analogic signal to a 24-bit value! More than enough I guess. Achim

Actually, an arduino is more than enough for what you want. you can have
data from 0 to 1023, that is >quite a lot, plus, you can use it directly on puredta using pduino, no need for OSC. I second that, arduino will do! But if you want to built an "pd-independent" device, you can use OSC in arduino - although much harder than simply reading values with pduino - some guys already posted code for sending OSC messages from arduino devices [1], so then you can plug it to whatever you want: pd, ardour, osc-to-midi apps, processing, supercollider :D

A gamepad would definitely be LESS precise as each potentiometer will map data between 0 and 255. But i've never found this to be a problem.

I guess it could, only Arduino is more expensive i suppose. I'll try to provide you with some pictures sometime soon.
