Step 11 - Calculate the length of four flexible wires
Use the ruler to build 25 pieces (each 4 wires). The length to become based on of photography (mm).
Step 12 - Separate each 4 flexible wire
Use a cutter to separate each 4 flexible wire. Make the same for 25 pieces that are made from step
11,10.
Step 13 - 100 pieces of heat shrink tubing (for 25 RGB leds)
Use cutter and ruler to create 100 pieces of heat shrink tubing. Use the length shown in the photo(mm).
Step 14 - Mark the wires
Mark one of the four wires with a marker to be recognized later (Corresponds to the first pin of each RGB led). Mark all 25 pieces.
