    Arduino - Keeping Outputs Low

    no probs. I just got into arduino and first thing i learnt is to activate pin 13 to do a self check of sorts.

    English Grammar is NOT Logical ;)

    http://en.wikipedia.org/wiki/Double_negative english is so messed up. the pronounciation of words is a great example ought (ort) thought (th ort) wrought (r ort) drought.... (dr out) I never understand how we can have the most common language but there are so many little annoying...

    don't know visual studio you will have to get someone better at coding, and someone who knows that program

    so essentially what you are doing is when one is high the other is low the electrons flow one way, when its opposite they flow the other way. when they are both low no electron flow when both high electrons short circuit

    if you put both to high you will end up shorting things

    well actually an easier way is to change both values to low, no power then

    the alternative would be a transistor on one of the wires(someone can show you a diagram I am sure) and connect it to the arduino with an additional code line on the pin you connected telling it to go high or low for on and off.

    put a power switch in there is the simplest way. on either of the wires leading to the motor

    The newbie's secret circuits circus

    ok back to this. does anyone know the current copyright laws? a post in the beginning linking to them will show that a person has copyright over material if it is truly unique and they can prove that they came up with it first. posting an idea on this forum will show a rough time of when someone...

    from the code given and the example I see in your first post there is no ""off" if the pin is low/off it rotates one way, if it is high/on it rotates the other. in digital electronics there is no other state.

    Odd LED question

    http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Components/LED/Top-Up%20LED%20Ring%20LED-CCL-A.pdf I found this product and the symbol for reverse current appears to be MICRO amps. so if I run the LED of a 9volt source I should use a resistor of 680kohms right? I got the red one found on page...

    Need help with arduino and L293D chip

    have you checked the battery directly with a multimeter or are you telling us that in your project it comes out as 0V ? finding a secondhand battery may be ok for some but as you are having issues already I will suggest getting a brand new, straight out of the box battery. this will definately...
