<r>Building a sensor node that publishes BME280 readings to a Mosquitto broker. asyncio + umqtt.simple combo works but had some sharp edges. Sharing for the next person.<br/>

<r>After yung shock ng REPL discovery (other thread), I went down the MicroPython rabbit hole. asyncio works on Pico, and once you wrap your head around it, much cleaner than blocking sleep() loops.<br/>

Quick example I wrote, logs a DHT22 every 30 seconds AND blinks an LED every 500ms, in ...

<t>Mga 1 hour lang ako on the Pico W with Thonny. Connected via USB, opened the REPL, started typing Python directly into the running microcontroller. Read a sensor in real-time. No compile-upload cycle.<br/>

Software dev ako, sanay ako sa "save file, run python script, see result" loop. To be ...

<r>Just got my first Pi Pico (regular, not the W variant). Coming from a few years of Arduino Uno/Nano work. So far impressed: cheaper than a Nano, faster, more memory.<br/>

Pero sigurado may catch right? May mga things kasi Arduino made easy that Pico does differently, at what point will I ...

<t>Background ko software (mostly Python web stuff for the past 8 years). Just started getting into hardware via the Pi Pico. Yung 'I know code but not solder' type ako, hopefully not annoying for the long-time hardware folks. May tanong na ako about MicroPython REPL, see other thread kung curious ...

<r>Sa C++/AVR register side, kabisado ni Tito. From the other side, kung gusto mong tuluyang umalis sa AVR timer Tetris, yung <B><s>[b]</s>Pi Pico's PIO<e>[/b]</e></B> (Programmable I/O) lets you write hardware-level PWM at any frequency you want, walang timer manipulation kelangan.<br/>
