Step 3Solder the LEDs and Resistors
Once you have the PCB made, its time to prepare the LEDs. I had some white SMD LEDs in PLCC package. But the size is not critical. Any size such as 1206 or 0805 would do too. Although a larger LED package is easier to solder. Similarly, for the resistor, a large package is recommended although I used size 0805 since thats what I had and it wasnt quite easy to solder this tiny resistor.
Solder the LED and the resistor at right angles as shown in the photograph. You would need 8 such LED-resistor pairs.
Ensure that the resistor is soldered to the LED Anode. You dont want a mix of pairs with resistors soldered to the LED cathode.
