If the external temperatures became extreme, the Pico W might permanently fail. Fortunately, enough external temperature sensors are already monitoring outdoor weather conditions. We can simply poll available APIs for JSON payloads containing current weather condition values. But rather than simply report the number, we can use colored bulb lighting to visually indicate whether it’s cold, comfortable, or hot outside. We’ll send ...
