                                       LED Current-Limiting Resistor (0805)                                      Tactile switch

Align the chip—noting the orientation of its dot

with the semi-circular mark on the circuit board.

SMD resistors have no polarity.

This is an LED current-limiting resistor

a resistance value anywhere in 

the 100Ω–1kΩ range is suitable.

Peel the chip resistors from the carrier tape use only two.

                          Connect to a 4.5–5V power supply.

                          Pay attention to the positive and negative polarity.

                          You will need to provide your own wires.

Tactile switches have no positive or negative orientation

whichever way they fit in is the correct way.

The longer lead of the LED is the positive terminal.

Insert it so that it aligns with the side 

marked with a "+".
