@Alpha.. i am totally new to this so don't know where to use these parts, have some basic (little more than just basic) knowledge of electronics (2nd year student Electronics and communication Engineering :P) but for arduino i am a noob. I am also going to start book "Getting Started with Arduio".
For the parts i googled and looked for various arduino kits
and these were the parts compiling all the kits.
2pF caps could come in handy with certain multiplexed LED control chips, such as from Maxim-ic.com, where speed & intensity are set with an external R & C.
Get yourself a 'scope too - download Virtual Analyser for a soundcard 'scope, or find a USB hardware item like dpscope.com. Some things you just can't check with a multimeter.
I don't know how big a GL-12 breadboard is.
Do you have wire for connecting things together?
Do you have perfboard or something to solder components to once you have a design you want to keep?
Having a 2nd pair of hands is often helpful - a Panavise or equivalent is handy when soldering.
Do you have other tools? wire strippers, needle nose pliers, things like that?
I am sure you'll be picking up some other specific pieces as you start getting into projects as well.
Isn't there a help file to download?
Ok, assuming not, just click the ON button at the top left.
I used it with a microphone in front of a speaker.
You can stick a 1/8"/3.5mm minijack in the microphone jack with a couple of twisted wires and do some playing. It can do A & B channels, so use a stereo jack.
With nothing plugged in, it is pickig up me humming via my laptops microphone, that is displayed on top.
The bottom shows frequency breakdown.
One of my favorite devices to have on hand is logic level n-channel power mosfets, great for when you need to switch something that requires heavy lifting.
newbie - visual analyser is a sound card oscilloscope - the hardware is the soundcard, the software displays the microphone input on your screen.
For example, this is me humming, with microphone pickup, and frequency meter selected
Probably don't want to exceed a volt or so for input.
I'll see if I can pick up a stereo jack tomorrow and provide some better guidance.
I would start with creating a square wave output from arduino into a potentiometer with the center tap and ground into the PC, slowly dial it up until the scope peaks out, then measure that and make up a scope probe with equivalent voltage divider for looking at 5v signals.
Crossroads Thnaks for letting me know ill try iy out
i can use them, but what are the voltage rating for that motors as i didn't find any rating printed on them
well generally motors can be run out of specs by a high margin ! you juse need to know the power consumption! generally small motors can be run off a l293 d i have a couple of 3kg cm torque motor and its power consumption is 400mA at a 4 kg load at 6V
