bornach, 1 year ago to random Pulsating PWM using two #LM358 dual #opamps configured as a fast oscillator, a slow oscillator, and a comparator whose output is the source of one LED and the sink of another LED No microcontroller required #electronics #OperationalAmplifiers #LEDs Breadboard prototyping of a 4 opamp circuit using 2 LM358 integrated circuits and a number of passive components, hooked up to an oscilloscope that displays the duty cycle of the output waveform slowly varying from 0% to 100% then back to 0% and the cycle repeats. A red LED gets brighter then dimmer, in antiphase with a green LED that goes dimmer then brighter
