where is amplitude on analog graph
Vertical on positive side measured in volts
where is peak to peak amplitude on analog graph
vertical on both negative and positive measured in volts
where is period on analog graph
Horizontally on one cycle. measured in seconds
Frequency formula
f = 1/T Hz
Duty Cycle Formula
Ton/TCycle x 100 %
the approximation of an analog signal by turning on and off a pin very quickly
Pulse Width Modulation
What is an N-type transistor
has more negative charges than positive charges. Electrons are majority carriers
What is an P-type transistor
has more positive charges than negative charges.
a type of diode designed to exploit the Zener effect to affect electric current to flow against the normal direction from anode to cathode
Zener Diode
what happens when the Zener diode reaches the Zener voltage
it reverses the current flow
what does AnalogWrite used for
uses PWM to adjust power supply
