Hello,
I have made a simple circuit to power a Led with Netduino using a NPN transistor to amplify the Netduino PIN base current (8mA) to 20mA for the Led. Now I want to drive more then one Led with more then one pin.I have to use a single transistor for each led ? Or is there a different solution ?
Thanks,
Paolo
If you want to drive more leds this way (up to eight), the uln2803 could be handy.

in this moment I haven't this component....so I can't drive more leds ?

Then you have to use a transistor for each output.
Ok...how I have thought...Thanks.
