Step 7Add a resistor for yellow and red LEDs

Add a resistor for yellow and red LEDs

Red & yellow LEDs draw too much power from a 3V battery and reduce battery life.

I used some 100 & 200 ohm resistors I had handy.

Wrap the resistor around one lead of the led, solder it, and snip off the excess.

I put the resistor on the lead that would later be soldered to the battery, thinking that would put less strain on it.
