[dorkbotpdx-blabber] [GroupOrder] order goes out monday feb 23. guest star: sure electronics

[dan p]

Just checked the first set of LED's and they call out

"20mA Continuous, 50mA peak for 10% Pulse Width" should be fine with the

and from the standard arduino spec

  DC Current per I/O Pin 40 mA
no problems, what is the worst that could happen? make a little blue smoke?
