Raspberry pi tutorial - Internal temperature sensor

In this episode we go straight to the Raspberry Pi Pico in VS Code to read the internal temperature sensor. We take the raw 16‑bit ADC value, convert it to voltage, then use the datasheet formula to get an actual Celsius reading. Then we wire up a LED on a GPIO pin as a dramatic little warning lamp: if the temperature crosses a threshold, we label it “critically high” and turn the LED on (otherwise it’s “good temp” and the LED stays off). Finally, we log the readings to a temps.txt file every 5 seconds using a context manager, flush writes for safety, and peek at the saved temperature history on the device.
