This library is using a hardware interrupt to monitor Echo pin state change instead of using pulseIn function which pauses code execution. The library enables the user to use this sensor with only 2-3 ...

The Time of Flight (ToF) sensor is significantly more accurate than the ultrasonic sensor. This is evident through the data shown above. Although the measurements were generally smaller than realistic ...

Focus on One Area: Robotics is broad. You could focus on programming first, then move to electronics, or vice versa. Trying ...

Somewhat reassured, I used the fully HA-integrated Claude Code to finish migrating most of my nearly 200 smart home devices.

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...
