Forrest Mim’s Stepped Tone Generator *with a twist

Forrest Mim’s Stepped Tone Generator *with a twist In this video we assemble the Forrest Mims Stepped Tone Generator ( Mims - 555 Timer IC ). The circuit uses a 556 with one side being set up as a free running oscillator and the other as a frequency divider. By adjusting the values of potentiometers on both the A and B sides we can charge the frequency and get some very interesting effects. But I wanted to do more and add a little something to the control voltage pin on the oscillator side. ************************************************************************* *Please help support this channel at NO COST TO YOU.
