    Odd LED question

    I have no issue with it, just read coca colas response. and then I found out the most interesting part which is the schematic is wrong. the circle is broken up into 4 sections. then each section has 4 LEDS. so in total the are 4 grounds (1 for each section) and 16 LEDS/anodes

    Odd LED question

    I see the common cathode is proving an issue, would this affect me if I was to use a 350ohm resistor on each and then light up more than 1 LED? also is it better to go with 330r or 390r? these I have

    the only reason I am doing this is for real time interaction with people who want to learn and may understand something I don't.....like alot of things lol

    Need help with arduino and L293D chip

    ok then, that is a big mistake, ALWAYS CHECK CONNECTIONS rule number 1. check to see they are both good connections AND they are not shorting

    How to protect the battery from being over-used and overcharged!!!???

    not me lol. I actually have started using a part of my brain a bit more, since I have been on here, that hasn't been used for a while. look at the arduino post I did for the X guy... took me a while to figure out how to get the off switch but I got there lol

    Odd LED question

    its a bargraph of sorts. but rather than being vertical or horizontal its circular. the issue is it cost $12 and I don't want it to blows up so if hyperthetically i was to hook it up to my arduino (only cos I can't find anything else right now) what size resistor should i look at, and should it...

    How to protect the battery from being over-used and overcharged!!!???

    you could start with solar garden lights if you have a few bucks spare. these are very dim (especially the cheap ones) but they have all of the components already. take one of these apart and try to learn each part and improve on them. My advice would be starting on the light, get the right...

    Computer monitor as TV?

    the EASIEST way to do this is take a laptop plug in a USB tv tuner card and then hook up the monitor. there are set top boxes that have VGA, DVI, and HDMI leads too though
