ELECTRONICS
Output Devices
Loudspeaker-electrical to sound
L.E.D.-electrical to light
Bulb-electrical to light
Buzzer electrical to sound
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
ELECTRONICS
numbers in a 7 segment
display can be produced by
using 7 L.E.D.`s
ELECTRONICS
There are 3 process devices,
The NOT gate
The AND gate
The OR gate
