Hello

I want to start with arduino, i've had a little basic things on school.
But I want more!
What must i buy? (ardiuno due, uno, mega, etc.)
What for sensors are easy to use?

Thanx, arder

Sorry for my bad english

Something like this should get you started:

http://www.adafruit.com/products/68

That has a Uno, some hook-up cables, LEDs, sensors, etc.

A lot of sensors are easy to use, it depends a bit on what you want to do.

If you can afford a bit more, how about the BOE bot?

https://www.adafruit.com/products/749

That's pretty cool, it has wheels and motors, sensors, etc.

The BOE bot does not include the Arduino however.

Thanx for the quick reply.

I think i go for a starters pack but there are more packs.
I found on this site a few:

It's a dutch site i hope it's not a problem

Good point. Add another $30 to get the Arduino to go with it.

The BOE bot, even after including the Arduino, is a great value if robotics is an interest though.

Of those choices, I'd go for the Sparkfun Retail one in "een stevige plastic doos", or the genuine Arduino kit "van de uitvinders van Arduino".

Have fun!

Also get a multimeter (doesn't have to be expensive).
Google forum search: Use Google Advanced Search and use Http://forum.arduino.cc/index in the "site or domain:" box.

Hell yes.... definitely a meter!

And also a few tools if you don't have them already: at least a pair of long-nosed pliers and a small Philips and flat screwdrivers. Most pliers have cutters built in, but you should also get a pair of side-cutters and maybe also a pair of wire strippers.

And a soldering iron.....

Budget permitting, a kit of tools is a good idea, see pic below. But beware the quality: some of those kits are really cr@p, and the screwdrivers can only be used once before they become paint stirrers.

uno ,
motor shield ,ethernet shields,Xbee,gyroscope will be useful.

I think that i buy the SparkFun Inventor's Kit:

  https://www.sparkfun.com/products/11236?

I want also to buy some tools and some additional leds and buttons.
With resistors do i need for that?

Leds:

blue
   
5.000 mcd
3.2 - 3.6 V
20 mA
20 graden
460 - 470 nm

yellow
5.000 mcd
1.8 - 2.2 V
20 mA
585 - 595 nm

green   
5.000 mcd
3.2 - 3.6 V
20 mA
520 - 525 nm

orange   
3.000 mcd
1.8 - 2.2 V
20 mA
20 graden
610 - 620 nm

Red   
3.000 mcd
2.0 - 2.2 V
20 mA
620 - 625 nm

white   
5.000 mcd
3.2 - 3.6 V
20 mA
NA

It's a simple calc to find the resistor for an LED, Arder...

Look up the LED voltage for the LED, as in your list... Subtract that from the supply voltage that you are putting onto the LED and its resistor... Then divide that by the LED current, and the result is the resistor you need. Then choose one a bit higher, to cut the current a bit more.

For example say the LED is 2V and 20mA, and you have a 5V supply. You need tom lose 5-2 =3V on the resistor, which at 20mA (0.020A) gives 3/.02 = 150Ohms so use say a 220.

I got a Sparkfun resistor pack with 500 resistors of various common sizes.
