Soldering of infrared LEDs

Next you'll solder IR LEDs as shown below.


Prepare the wires and 470 ohm registor soldered IR LEDs.
9cm x4, 15cm x2, 45cm x2, 50cm x2



Solder this LED as shown below.



Put heat-shrink tubes.



Solder the other LED.


↓



Solder the remaining LEDs. You cannot put heat-shrink tubes after the soldering so make sure to put the tubes and then solder.

Solder the 45 cm wires to the board.

Soldering of the Cue LED

Solder green LED to 90cm wires.


Bend the leads around 80 degree.


Cover the metal parts with epoxy adhesive as a waterproofing.


Solder the wires to the board as with the below.

Soldering of servo cable

Remove the male connector from the servo cable and extend it if the length is less than 50 cm.


The below is an example of the extending of the cable.
Tips to extend wires


Solder the wires to the board. In this photo, Black is ground, white is 5V and red is control signal (PWM). Check manual or manufacture homepage to find which color shows which line.



If the borad has separated power rails, connect them with soldering.

Soldering of wires for Arduino connection

Prepare 5 jumper wires with male connectors.


Remove unnecessary connectors.

Solder each cable to each line as shown below.

Soldering of ventilation fan

Prepare 4cm fan.



Extend its cable if it length is less than 50cm.



Solder the wires to the power rails of the board.



Finally, check the underside of the board for any remaining cut lead or wire or lead that you forgot to cut.





The wiring is now complete.
