As I really prefer Python for my little projects over C++, I flashed my Wemos boards with Micropython and wanted to share how I did it (it was pretty easy). You have to connect your board with USB to your computer, have Thonny installed and the desired micropython image downloaded. (You can do it with…
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…
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…
Materials you need for this: LDRs (I am using 5528), breadboard, jumper wires, resistor (I used 56k) and a 5V power supply. The MicroPython code has been written for and tested on Pi Pico, Pi Pico W, D1 Mini and NodeMCU v3 ESP8266 .I bought it at berrybase.de and az-delivery.de (not referral links). The microcontrollers…
Great microcontroller, bought it at az-delivery.de (no ref link). The onboard LED pin is 2 (GPIO 4).
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…
