90. Phase-shifted Sine Wave

Use any microcontroller to generate two sine waveforms on two GPIO pins. Use a potentiometer to control the phase shift of the second sine waveform.

  • Waveform 1: Sine wave.
  • Waveform 2: Phase-shifted Sine wave.
  • Potentiometer: Adjust phase shift (0 to 360 degree).

Note: We can generate a sine wave using the built-in DAC of the ESP32 or similar microcontrollers.
