Schematic Diagram


  1. Turn  the PCBoard over so that you are looking at the PLAIN side.  From the drawing, find the locations of the components.  You will need to turn the PCB around so  that  it  coincides  with  the  placement  sheet.  Remember that you are seeing the copper track through the PCB.
  2. Bend  the legs of the resistor to a shape that will fit into its two location holes.  Push them through and firm the resistor down against the PCB. See Resistors.  
  3. LED's are "Light Emitting Diodes". .Spread the legs of the LED carefully  so  they  spring  into  its correct holes.  Push the legs just through the PCB so the LED stands high off the board.  You should check that the small flat on the flange at the base of the globe is the same way round as the drawing shows.  The LED is polarised  -  a semiconductor - and will not work if placed the wrong way round.  See Diodes  
  4. These two components may be soldered in place. Refer Soldering Technique .
  5. Push the ends of the battery snap wires through, and solder.
  6. Push the PCB pins into the correct holes and solder.
  7. Bare the ends of the hook-up wire, tin both ends - refer Tinning wire.  Solder one end to one PCB pin. 
  8. Solder the teardrop terminal to the other PCB pin.
  9. If  you  are  fitting a BUZZER, make sure you observe the correct polarity.  Solder the RED (+), and BLACK (-) 
  10. Connect a 9 volt battery and test by touching the end of the wire to the teardrop terminal.


If it doesn't work check that you have all the locations correct and that  you  have  the  LED  in  the correct polarity.
