hey guys, lets see, i got a little rocket fuse, and when i took apart its original launcher, i saw that it uses exactly 6 volts to make it firey red, and hot enough to light the rocket, now i thought the arduino would be enough to power it ( 5v, 6v whats the diffrence?) but unfortunitly its not! so is there a way to kick it up another volt, without blowing out the arduino, cuz i know output = 5v, and if i input more then 5v, then it gets bad. so can i like add a battery to the positive side of the outputed pin, and then put a resister on the ground side, or will that make the circuit less volts from the begining?

thanks!!

the arduino pins cannot supply enough current, you'll need to use a transistor. you should post to the arduino forum, since this question isn't really related to the starter pack.

ok, thanks ladyada!, btw just for refrence, a transister, makes voltages higher, with a little 3 pin half circle thing, right? and also is there one that only increases what you want by 1 volt, because i think anything above 6 volts could be dangourus...

also, is a transister safe to use, with the arduino, and the proto sheild ( in the tiny breadbord... )?

again, you should really take your questions to the arduino.cc forums (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl), as they are there to help beginners like you with questions.
this forums is really only intended to help people with the tutorials on ladyada.net
