Always look on the bright side of life: An adaptive night light for RGB LED stripes in MicroPython
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…
YFNWG – your friendly neighbourhood washroom guard. IoT thresholded Temp/Hum/Open sensor with MicroPython on a D1 mini
It measures the temperature, humidity and open status of a window and send the values to the local MQTT broker if the values have changed (enough). The D1 got a nice housing on a solderable breadboard. The sensor cables can be plugged and unplugged into sockets on the breadboard. So I can easily exchange the…

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…

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)….

I don’t like grilled cheese – a thresholded IoT (MQTT) DHT22 sensor on with a D1 mini written in MicroPython with circuit diagram, casing and installation
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…
