PCB DESIGNATORS

You can choose any type and color of diode led. The resistors set the brightness, recommended values for a normal led are from 2.2k to 4.7k Ohm. For high bright leds, you should use higher values for the resistor, from 10k to 22k Ohm.

GENERAL DESCRIPTION OF COMPONENTS

Resistors

The resistors are ¼ Watt metal type. You can either use a multimeter or the color bands to obtain their values. Resistors don’t have polarity; you can assemble them in any direction.

Led diodes

Led diodes have polarity, the cathode is indicated as a flat surface on the side of the diode and also it is the shorter led. On the PCB, the cathode is marked as a flat side and anode as a round side.
