Interesting... I use it on my desk to keep the air from blowing my papers away. |

Hello my friend, I think it would be rude of me to answer you in Portuguese given that we are in a english forum. Im also a beginner but I believe I can help you. If you need assistance with that experiment email me at: thiagomelogomes@yahoo.com.br |

I saw some tutorials of people scraping the pots to decrease the resistance, so maybe I could get up to (or closer to) the full 5v? But, I don't see a way to easily do that with the one I have. --- End quote --- By the way, scraping the conductive trace in a potentiometer would increase its resistance, not decrease it. |
