I am an absolute beginner when it come to physical computing. I have just bought a RPi starter kit of electrical components from ebay. It has 220, 1k and 10k ohm resistors. Any of the LED projects I've seen use 330 ohm. Will it damage my Pi if I use the 220 ohm? Can anyone recommend a really good beginners site for to learn electronics, more especially breadboard. I have Googled but there are so many it's confusing. Thanks.
