. 

(A) Slip the tubing over each lead. (B) Us-

ing the shaft of the hot soldering iron, shrink 
the tube until it is snug.

NOTE: NEVER USE THE TIP OF THE SOLDERING IRON 
TO SHRINK THE TUBING. YOU WILL DAMAGE THE TIP.

. 

(A) Strip 1/4” off the opposite end of each 

wire. (B) Twist the wires together. (C) Repeat 
steps 1-5 for the blue LED. (D) Mark the blue 
LED in a way (using tape, for example) so you 
can later distinguish the red from the blue wires.

. 

(A) Twist together both sets of LED wires. 

B) Cut 1/4” of heat shrink tubing. (C) Slip the 
tubing over the wires, positioning it close to 
the end as possible. (D) Shrink the tubing in 
place.

. 

Your final LED set should appear similar to 

the one pictured above.

1

. 

(A) Cut two 18” lengths of wire and strip 

1/2” off of each wire. (B) Cut the two prong 
connector off of the piezo speaker. (C)  Strip 
off 1/4” of each speaker wire. (D) Twist one 
18” wire to each speaker wire. (E) Solder the 
wires together.  

NOTE: TRIM THE SOLDERED CONNECTIONS IF THEY 
ARE LONGER THAN 1/4” IN LENGTH.

. 

(A) Cut two pieces of heat shrink tubing 

slightly longer than the soldered connections (a 
little more than a 1/4”). (B) Next you will solder a 
two pin header to the opposite end of the wires. 
This will make it easier to connect the speaker to 
the PCB later.

3

. 

(A) Strip 1/8” off the opposite end of each 

wire. (B) Use the putty to the stabilize the pin 
header. (C) Slip the stripped ends of the wires 
into the holes of the pin header. (D) Solder the 
wires in place by filling the holes with solder.
