BS2 power question...

roughwire

I need to wire up 21 LEDs (in groups of 7) that will just blink how I programm them. Simple. But the only thing is, the 9v battery connected to my board of education doesn't have enough power to light up even 4 LEDs at once... Now can I send some more power through my stamp w/out hurting anything, or is there a limit?

If you need to light many leds you need to make sure you can do it directly from your power source. If that works you can hook the leds to a transistor and turn the transistor on and off with the stamp.
