About the hc sr04 sensor.
HC-SR04 Library
-
Hello. I tried 2 different libraries for ultrasonic sensor HCSR04, but they both make my stepper motors to work slower (I guess because they use in code "delay" or something to change frequency). Do you know any other library that will not create such problems? (Link of the libraries I used in comm)
This is the first library I tried: https://github.com/gamegine/HCSR04-ultrasonic-sensor-lib

Monitoring my home's air quality with AirGradient's DIY sensor
Not sure if this is DIY enough for you, but I'm using an MQ131 (about $20-$30 on Amazon, probably cheaper directly from China) in an air quality sensor I'm building. There's an Arduino library for it [1], and from what I can tell so far, it does work, though it's probably not super accurate. It's also somewhat sensitive to environmental factors, though you can correct for some of that with known temperature/humidity.
