List of topics Power supplies: 5 Volt power supply Unregulated mains power supply Sensors Door switch Pressure Mat PIR detectors Temperature sensors Light sensors Infrared Light Beam Optical Computer Interface Sound sensors Microphone pre-amplifier for long cables Sound level detector Vibration sensors Proximity/touch sensors Position sensors Distance sensors Speed of movement sensors Direction of movement sensors Limit and position switches/sensors
Signal conditioning Variable resistance sensors Signal level switches Signal level switch with dead-band Differential amplifiers Differential amplifier used to provide an offset Summing amplifiers Inverting amplifiers Differentiators Analogue to digital converters
Prime Movers (motors etc.) Turning motors on and off Changing direction of movement Changing direction of movement using electronic switching Speed control Limit switches Servos Stepper motors AC motors Solenoids Pneumatics Lights LED’s LED switching circuit Incandescent (light bulbs) Fluorescent Neon Lasers Sound Sound mute with pause output Low power audio amplifier Speech recorder and playback
