Step 19Better Red
Red LEDs generally have a lower voltage drop than green LEDs, so we'll use five instead of four.
Try twisting five of them together and running the ensemble off your low 9V battery or good battery and 330 Ohm resistor. If the LEDs seem too bright for their own good, you'll have to incorporate a higher resistor or perhaps change the design or change the LEDs, but most likely it will all work out.
Twist the five red LEDs into a pentagonal shape, or make a bow out of them, or any other shape that strikes your fancy. Here's your chance to go crazy!
