LED Rainbow - RGB LED PWM Controller Construction - Easy To Build

Step 8 Assembly Step 5: Resistors R1, R2 and R3

We now move on to the three resistors at R1, R2 and R3 which are 1K ohm resistors and have a color code on them of brown-black-red-gold. Resistors are not polarity sensitive so these can go on any way. Bend the leads so you have the resistors standing on end and solder R1, R2 and R3 into place.
