Resistors

Resistors limit the current flowing through them. The higher the resistance value, the less current will pass through it.

Resistors have no polarity, which means you can insert them in either direction (i.e., you can safely rotate 180°).

Install and solder resistors R1 and R2 then clip their leads.

WHAT DOES IT DO?

R1: prevents a pop sound when switching

R2: limits current available to D1
