\a[../../rpi-pico-w/upython/adc.py]: <analog-to-digital converter>.

The program continuously prints to the USB the value of the ADC on GPIO 26 once every 0.2 seconds.

The onboard LED is blinked as a <heartbeat (computing)>.

The hello world is with a <potentiometer>: extremes on GND and VCC pins of the Pi, and middle output on pin GIO26, then as you turn the knob, the uart value goes from about 0 to about 64k.

The 0 side is quite noisy and varies between 0 and 300 for some reason.

In <Ciro's ASCII art circuit diagram notation>:

Toggle pin 0 twice per second. This could be used for example to blink LED on pin 0 once per second with this test circuit:

``
BOARD__1gp0____3gnd
       |       |
       R_2k    |
       |       |
       +-aLEDc-+
``

Tested on:

* <RPI Pico W>
