5. Wires to the LEDs

Obtain the super bright LEDs. The first one to select is the blue one. The blue ones are ‘clear’ coloured, as they do not have the yellow tinted phosphor. Step 1-4 is to be repeated twice for each blue LED.

With the wires that were cut in the initial part, obtain the 38cm positive and 38cm negative wire. Strip the ends of the wire and tin the tips.

Solder the positive wire onto the terminal of the LED that has the + labeled next to it. Solder the negative wire onto the terminal of the LED that has the – labeled next to it.

Here is a closer look at the soldering. Ensure each wire is connected securely. Repeat step 1-4 again for the second blue LED.

Obtain the white super bright LED. This one has a yellow tinted phosphor.

With the wires that were cut in the initial part, obtain the 42cm positive and 42cm negative wire. Strip the ends of the wire and tin the tips.

Solder the positive wire onto the terminal of the LED that has the + labeled next to it. Solder the negative wire onto the terminal of the LED that has the – labeled next to it.

Here is a closer look at the soldering. Ensure each wire is connected securely. Repeat step 5-7 again for the second white LED.

Congratulations! You have completed the soldering of the LEDs.

Here is a closer look at the LEDs if it is of any assistance for double checking.

Insert the first white LED into the screw terminal labeled ‘LF’. The negative wire goes in to the terminal with the thicker white line on the circuit board.

Using a screwdriver and proper bit, loosen the screw terminals prior to inserting the wires. Then, tighten the screw terminals.

This LED will be for the front left of the robot.

Insert the first blue LED into the screw terminal labeled ‘LB’. The negative wire goes in to the terminal with the thicker white line on the circuit board.

Using a screwdriver and proper bit, loosen the screw terminals prior to inserting the wires. Then, tighten the screw terminals.

This LED will be for the back left of the robot.

Insert the second white LED into the screw terminal labeled ‘RF’. The negative wire goes in to the terminal with the thicker white line on the circuit board.

Using a screwdriver and proper bit, loosen the screw terminals prior to inserting the wires. Then, tighten the screw terminals.

This LED will be for the front right of the robot.

Insert the second blue LED into the screw terminal labeled ‘RB’. The negative wire goes in to the terminal with the thicker white line on the circuit board.

Using a screwdriver and proper bit, loosen the screw terminals prior to inserting the wires. Then, tighten the screw terminals.

This LED will be for the back right of the robot.

Congratulations! You have completed adding the LEDs.
