Step 11LED and Switches Add-On
The most important part of this step is making sure you have the polarity of the LED correct. I would highly recommend checking this with a multimeter. If you don't have a multimeter available here's some tips:
2. Solder one leg of each LED, verify the alignment and make corrections as necessary.
3. Apply solder to the other lead, make sure the first lead is adequately soldered and clip the excess.
4. Insert the 5 momentary push buttons. Solder and clip the excess from the legs.
- The LEDs in my kit had the positive lead (anode) a bit longer than the negative lead
- If you look in the "plastic" case of the LED you will see a large and a small conductor. The larger conductor will be the negative side of the diode.
