Build Instructions
Before you start, take a look at the Printed Circuit Board (PCB). The components go in the side with the writing on
and the solder goes on the side with the tracks and silver pads.
Start with the seven resistors, R1–R7, which are all 330 (orange, orange, brown coloured bands).
The text on the PCB shows where R1, R2, etc go.
Solder the Integrated Circuit (IC) holder into IC1. When putting this into the board, be sure to get it
the right way around. The notch on the IC holder should line up with the notch on the lines marked
on the PCB.
Insert the switch into the board where it is labelled SW1. Once you have got the pins lined up with the
holes, they can be pushed firmly into place and soldered.
Solder the seven Light Emitting Diodes (LEDs) into LED1 – LED7. The LEDs won’t work if they do not
go in the right way around. If you look carefully one side of the LED has a flat edge, which must line
up with the flat edge on the lines on the PCB.
The battery connector should be soldered into the ‘Power’ terminal. First feed the power clip
through the strain relief hole next to the power connection. You should feed the wire from the
solder side of the board. The red wire must go to the ‘+’ terminal (also marked ‘red’) and the black
wire must go to the ‘–’ (also marked ‘black’) terminal.
The IC can be put into the holder ensuring the notch on the chip lines up with the notch on the holder.
Connect the PP3 snap on to the 3xAA battery box. Do not use a 9V battery with this circuit as it will destroy the IC.
