I
n this experiment you will be creating an oscillator
circuit that doesn’t make sound using a speaker or
an earphone. Instead the circuit will produce light
w
ith an LED. This will give you an idea of how
larger strobe lights work. When you press the key,
watch LED 1. At certain intervals the light turns on
and off. With the 50kW control you can control the
rate of blinking.
Try substituting a capacitor with a lower value for
the 100mF capacitor to see how an oscillator works.
Make a prediction about what you think will
happen? Were you correct?
