Experiment with two 555 #3.
Analyze the use of 555 to generate pulsed signal with two pulse trains alternating in two voltage ranges: one between 0V to 3.89 V, and another, between 3.89 and 7.76V.
In this configuration, the change in frequency of each 555, resulting from the manipulation of their pots, yields very interesting results , noticeable by the analysis of signals in the " oscilloscope " or the brightness of the LEDs .
In other words, the first output 555 modulates the output of the second.
Good fun!
