Periodically Vary PWM Duty Cycle (SPWM) without any Microcontroller | 555 & OPAMP | LED Fading | DSO
Sorry for late upload.
This video will let you on how to generate PWM of periodically varying Duty Cycle, or Sinusoidal PWM (SPWM), to create fading effect in LED without using any microcontroller. Only discrete components like 555 and OPAMPS to be utilized. The video will explain circuit diagram, working and DSO waveforms. Please comment for any confusion. Do like, comment and subscribe
