thnx that makes more sense smiley

thnx smiley

hmm sort of, might need a diagram if its possible smiley

this is the bar sport section smiley-wink ie: non arduino goes.

it will probably be driven direct from soundcard/mp3 player. I could probably drop the voltage a bit b4 it is need be, i just want to try it out so i an understand more, like i said i have seen the kit but they give no info about it and the image was too small to se the resistor values.

anyone? :o I'm still searching but haven't found anything yet smiley-sad

realy could do with the help, I know its prolly simple but thats only if you know how..

Can someone help me out? smiley

I want to make a simple LED meter (VU?) that comprises of 5 LEDs, 2 green, 2 yellow, and 1 red, voltages at 2.2 and 2.3 volts.
I need to know what resistor values i would need. This circuit does not use any chips or transistors (i have seen the kit but no schematic)
all it uses are LEDs, resistors, and a diode, a capacitor too.
Its use wil be for adding into some speakers, or on the front panel of a pc to show sound level, and I really want it simple as possible, no chips or transistors (I cant get them easily), resistors and LED's I can get easily tho. and the kit i have seen online only uses them and a diode and cap.

Can someone throw up a diagram and list suitable resistors for such a thing please? smiley i am still learning this stuff and this will help.

thnx smiley-wink

Oh my god its taking too long to get here smiley-sad i want to make things and i cant wait for the Arduino to arrive  :'(

why is it taking so long smiley-sad (hope its here tomorrow)


{Edit} YaY its here smiley-grin (runs off to warm up soldering iron smiley-razz )

I just salvaged a MC14049UBPC chip, along with a few other bits, from an old Velleman metronome kit (from Maplin UK), and looking for the data sheets online i found it can be used for driving stepper motors smiley

So i should be able to use it in tandem with my Arduino smiley-grin

gonna experiment with the schematics i have to make sure it runs ok tho. smiley

Thanks I'll look into it smiley

i got a few bits an my components box, and harvested stuff from other things.. i just wanna get used to the thing b4 i go gung-ho with it smiley-grin

I just ordered my 1st Arduino board off of eBay and am waiting for it to arrive smiley

in the meantime i am looking into what i can use it for smiley-grin i like the servo controller ideas and many others i have seen on this site and other Arduino sites smiley-grin

cant wait to try things out.. gonna be prepping my breadboard, making jumper wires, and borrowing my servos from my RC plane smiley

is there a way of driving a stepper motor directly from the Arduino? as i cannot get hold of any extra components at this time smiley-sad

Bng.

It would be nice to see such options for uploading to the board as usbtiny, and paralell, and so forth, other than just the com port list.
it would simplify it alot and remove the need to dig out the prefs file and change the 'upload using' line to whatever device u are using. (personally i have taken a liking to the usbtinyisp, much more stable than the paralell cable smiley-lol)
ay chance of this implementation into v1.0 ? :3
