ASSEMBLING THE PCB

1
ASSEMBLING THE PCB
Your PCB has two sides, a COMPONENT side and a
TRACK side. The view below shows the component
side.

ASSEMBLING THE PCB
First insert R1, the 330 ohm resistor.Note the
colours, orange, orange, brown.

The next two resistors, R2 and R3 are both 4.7
Kohms.Colours Yellow, purple, red.

Now insert the Zener diode. It is very important
that it is inserted the correct way round. The
band at the end is facing to the left.

Next insert the IC holder. It has a notch at the
top denoting which end is the top.

ASSEMBLING THE PCB
There are two capacitors. They are both the same
value, 2.2uF.They also must be inserted the
correct way round. The stripe denotes the
negative leg.
negative leg.

Finally for the component side, insert the
buzzer. The positive connection is the longer leg
and is at the top.

Now turn the PCB over to look at the COPPER TRACK
side.
9
ADDING THE LED
Add the LED. This can be any colour you choose.
The longer leg is the positive connection and
faces upwards next to the sign.Dont push
the LED in too far, leave about 5-10mm gap from
the PCB.
