For my Chibi Totoro plushie, I wanted to use 3 white LEDs and 1 blue LED, to create a ghostly effect.
The circuit diagram using the battery packs we purchased should be as follows, using:
- 3 x AAA batteries at 1.5V each = 4.5V
- 1 x blue + 3 x white LEDs
- 4 x 68 ohm resistors for white and blue LEDs
