Presentation Transcript

  1. ELECTRONICS An electronics system has 3 parts – input , process , output

  2. ELECTRONICS

  3. ELECTRONICS Input Devices Mic-sound to electrical

  4. ELECTRONICS L.D.R.-Light to electrical Thermistor-heat to electrical

  5. ELECTRONICS Thermocouple-heat to electrical Switch Solar Cell-light to electrical

  6. ELECTRONICS Output Devices Loudspeaker-electrical to sound L.E.D.-electrical to light Bulb-electrical to light Buzzer electrical to sound

  7. ELECTRONICS Relay-electrical to movement L.E.D. has to be protected by adding in a series resistor to take some of the supply voltage

  8. ELECTRONICS numbers in a 7 segment display can be produced by using 7 L.E.D.`s

  9. ELECTRONICS There are 3 process devices, The NOT gate The AND gate The OR gate
