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.

rpi-pico-w/upython/uart.py 2025-07-26
Any
print() command ends up on the USB, and is shown on the computer via programs such as ampy get back.However, you can also send data over actual UART.
We managed to get it working based on: timhanewich.medium.com/using-uart-between-a-raspberry-pi-pico-and-raspberry-pi-3b-raspbian-71095d1b259f with the help of a DSD TECH USB to TTL Serial Converter CP2102 just as shown at: stackoverflow.com/questions/16040128/hook-up-raspberry-pi-via-ethernet-to-laptop-without-router/39086537#39086537 for the RPI.
rpi-pico-w/upython/blink_gpio.py Created 2025-07-26 Updated 2025-07-27
Same as the more generic micropython/blink_gpio.py but with the onboard LED added.
rpi-pico-w/upython/blink.py 2025-07-26
Blink on-board LED. Note that they broke the LED hello world compatibility from non-W to W for God's sake!!!
The MicroPython code needs to be changed from the Raspberry Pi Pico 1, forums.raspberrypi.com/viewtopic.php?p=2016234#p2016234 comments:
