1, Place the IP3, P8, P5, OP2 and OP1 modules onto the Bridge Power Base (see Fig 8.). Connect up the OnTrack module to hold these down. 2, Using 6 white leads and 4 crocodile leads connect up the system as shown. 3, Turn the 500K variable resistor in an anticlockwise position so that it is set at its maximum value. 4,

Testing and Investigating: 1, Press the push switch on IP3 and the L.E.D. should light and the motor start to turn. 2, When the motor has stopped, due to the Monostable going back to the off state, repeat 1 again but this time press the limit switch whilst the motor is turning. Check that it resets itself i.e. the motor and LED turn off. 3, Press the strip of card that represents the door onto the motor and check that when it has turned through a right angle it is able to come into contact with the micro switch lever. Repeat 1 above to model the swinging automatic door.
