starting with arudino (once again)

right. sorry for that, but i used to work only with trackers and puredata and broken radios lol, so dont know that much bout interfaces and electronics. i would like to start with connecting myself to the arduino interface, so i guess starting with piezo attached to the wrist wouldnt be a bad idea.

i got the arduino booklet and the breadboard seems essential. what else would you recommed?
