PWM Output Test

This is a simple basic test for the PWM output.

We just send a generated sine wave to some defined pins and expect to hear some audio signal.

Output Device: Piezo Electric Element

To test the output I am using a piezo electric element

DAC

You can also use some simple earphones

DAC

It should also be possible to connect a headphone to the output pins...

The pins depend on the Processor:

PIEZO ESP32 RPI Pico MBED UNO R4
+ GPIO4/GPIO5 GPIO2/GPIO3 GPIO2/GPIO3 GPIO2/GPIO4
- GND GND GND GND
