 At championship, as we do at every regional, we'll be counting every point scored (or lost) by each robot. Nothing beats numbers. - Derek Bessette [more] |

Re: bells, buzzers, and whistles
Thanks!
It says 300-500hz, so I'm guessing it includes a switcher. Apparently the digital module can put out 64mA, but I think I'll use a small transistor to amplify it. 6V*20mA = 120mW. A 2N2222 should do fine, but I hope the buzzer will run on 5V. |
