1, Place the IP2, P7, and OP1 modules onto the Bridge Power Base (see Fig 1). Connect up the OnTrack module to hold these down. 2, Use four white leads to connect the IP2 module to the 20 K Variable Resistor and the 100uF Capacitor on the component card 3, Use four more white leads to connect the Fixed Tone Piezo Sounder (Buzzer) and the L.E.D. to the OP1 module. Ensure the polarity is correct (i.e. your + and - connections). 4,
Check all your wiring is accurate and then connect the 9 volt power
supply. |

Testing and Investigating: 1, The system is simply switched on by pressing the push switch on IP2. 2, Adjust the 20K variable resistor on the component card so that its arrow points down to the 6 O'clock position. This should produce a bleep approximately every second. 3,
Adjust the 20K variable resistor throughout its range and notice the
different output effects produced. Decide which type you feel is the
most noticeable. Further Circuits : Replace IP2 with IP1 and P6 then connect up using a light sensor circuit as an input. Can you make the output devices work now?
