The onboard LED is at GPIO 2.
The pinout of Pi Pico and Pico W are the same. Just the onboard LED has changed. See below.
This is a continuation of Is it dark yet ? – Measuring brightness with LDR on Pi Pico (W) and ESP8266 (D1 Mini & NodeMCU v3) in MicroPython, but concentrating on a fast and clean code rather than how to use a LDR with MicroControllers in principle. What you need: D1 mini or a similar…
Great microcontroller, bought it at az-delivery.de (no ref link). The onboard LED pin is 2 (GPIO 4).
Jump to: Pico – D1 mini – Pi Zero Raspberry Pico A short Python implementation of a magnetic switch turning on a LED when it is not connected (e.g. window is opened). For simplicity reasons I used the builtin LED on the Pico. You have to use the pull=Pin.PULL_DOWN parameter for the input pin (sensor)….
TLDR: An IoT sensor for temperature and humidity sending its values to a local MQTT server. Measuring interval and thresholding easy to configure. So much to write about a pretty small device and less than 100 lines of code including configuration, prints and comments. Hope you enjoy it! 🙂 I really like building and writing…
This covers a very configurable and more complex variant of measuring brightness and turning on LEDs.If you are looking for a more basic variant: It all began with a LDR and curiosity. The result is a night light for a ESP8266 like D1 Mini or Raspberry Pi Pico (W) which compensates darkness with many configurable…
