Hi!

I wonder if there is a way to measure the remaining voltage of my 9V battery supply connected to my BoeBot on BS2.

Anyone knows how?

John.

    You'd need to measure it with an ADC circuit. Dr. Tracy Allen has done some work using simple components and RCTIME. His web site is a great resource: www.emesystems.com.

    Jon, thank u. I really appreciate it.

    I'd like to ask you if capacitors included in BoeBot Full Kit are proper for that kind of stuff, since Dr. Allen used "polystyrene or polycarbonate film capacitors".

    What do you think?

    John.

    Dr. Tracy is a very sharp cookie (and a cool guy, too) -- I'd follow his advice on this one.
