1st arduino program

i completed the "setting up breadboard" lab, then moved on to the arduino board.
identifying the resistors was a challenge, i was able to find very helpful references on the web (i will eventually put them up). never knew there was such a sophisticated system behind those colorful stripes...
after setup, i downloaded and installed software only to find that the computer i was working on was too much of a dinosaur to handle it (mac OS X 10.3.9 powerpc driven). i plugged my arduino in, green light went on, no detection in serial port though. i troubleshooted for awhile, but instead convinced my roommate to let me use his macBook bought just last feb.
downloaded and installed software on his comp. and success! there was my board in the serial port, now for the programming

completed the arduino program. yellow led is on, push button, red led is on.
