Step 1: Parts

1.arduino
2.breadbord
3.usb cable
4. 4 leds
5. 4 330 ohm resistors
6.10k pot meter
7. and fun

Step 4: Tree

then in sert the pot meter
connect
pin 1 to ground
pin 2 to analogpin 0
pin 3 to +5 v
oke youre al done now yust

There's also another way to achieve this, but this is also correct and a fun beginners project. The other way to make this cuts down on the amount of resistors. Instead, connect all of your LED's to a single resistor which connects to +5v. Then connect the other side of the LED's to the I/O pins. Then say you want LED 1 on, you would then write that pin LOW, so that current flows through. To turn it off, write it HIGH. Have fun and keep experimenting.
