Similar circuit configuration as last experiment (Astable Multivibrator). When the switch is turned on, the LED lights and one hears sound from the speaker. Turning the variable resistor and the frequency of the sound changes. The LED appears to be solid bright then dim but is blinking about 500 times a second (due to the small disc capacitors). In the second video, I replace the disc capacitors with the 100 and 10 microfarad capacitors to make the frequency rate much lower.
