Miscellaneous Circuits (Part Two)
From the Technology Enhancement Programme (TEP), these circuits allow students to build a range of devices. Each circuit has a full circuit diagram, component list and explanation of how the circuit works. In this section, the circuits cover a range of miscellaneous devices.
Fuse tester
This Circuit denotes if a fuse is faulty or serviceable.
Simple torch
A circuit with a lamp that lights when the battery is connected and switches off when a push-to-break switch is pressed.
An OR gate
A circuit to demonstrate the OR function. When switch 1, or switch 2, or both, are pressed, a motor rotates.
An AND switch
This circuit demonstrates the AND function. Switch 1 and 2 must be closed for a motor to rotate.
A two-way switch
This circuit demonstrates two-way switching action.
A dimmer switch
This circuit demonstrates how the brightness of a bulb may be controlled by a variable resistor.
A continuity tester
This circuit can be used to check for breaks in a conductor, a faulty fuse, a faulty bulb or other device.
Steady hand game
The object of the game is to try to pass a small circle of wire along an erratic loop of wire without touching the loop. In the event of the circle touching the loop (even momentarily), the buzzer will sound and remain in that state until circuit is reset.
Test your grip
This fun circuit is used to test strength of grip. As grip is tightened on the sensors, progressively more LEDs will light.
Majority decision
This circuit could be used to judge a contest. When two or more judges give a positive vote, the contest is 'won'. If only one or no judges give a positive vote, the contest is 'lost.'.
Quiz controller
When either of the contestants from a particular team press their switch, the lamp associated with their side will light, with exclusion of other teams lamp.
Single pulse counter
In this circuit, a seven-segment display will be incremented by one each time a pulse is produced by closing and opening a push-to-make switch.
