1, Place the IP1, P2, and OP2 modules onto the Bridge Power Base (see Fig 2). Connect up the OnTrack module to hold these down. 2, Use two crocodile leads to connect the OP2 module to the motor. 3, Connect two more crocodile leads to the top inputs of IP1. When connected together they allow current into the Darlington Pair amplifier (P2). 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 gripping the two seperated crocodile clips that are connected to IP1. A small current flows through your fingers and is amplified by module P2 to switch on and drive the motor. 2,
Reverse the connections to the motor and try the above again. What happens
to the direction of motion? Further Circuits Add OP1 to your system and connect to it other Inductive outputs that you can find in the workshop such as electromagnets, solenoids.
