this tutorial looks pretty sik. I am confused about the LEDs and resistors and such though
. Mabe sumone with sum technical/electrical know how can answer:
Which LED and Resistor should i use?
I have decided to use a 5V LED because i think i wont have to use a resistor... Is it true? and if a resistor is needed, which one like how many ohms?
And second question is do i NEED to solder the LED or could i use electrical tape or sumother means of doing it. (I do not own a soldering iron or a dremmel
Plz and thx
