hey there, i'm not an familiar with electronic stuff..
i'm planning to make my name out of 50-70 LEDs just for fun.
i'm planning to use a 9V battery(the square type) to lit up all the 50-70 LEDs.
So,
1) do i need a resistor for all my leds?
2) if possible, can teach me how to solder the circuit? so tht i doesnt need to use resistor
thanks!!
