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 3.75V, and another, between 3.75 and 7.5V. In this configuration, the frequency of the first 555 determines the time of switching between the pulse trains of voltage ranges having the second detemines the frequency. In other words, the first output 555 modulates the output of the second. I added a capacitor for output to soften the waveform and therefore the flashing of the LED. Try to increase and / or decrease the capacitance of this component and observe the behavior of the output , the LED or the oscilloscope. Good fun!
