In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

Sound! It’s a thing you hear, moreso than something you see with your eyes. And yet, it is possible to visualize sound with ...

CMU researchers paired acoustic resonance sensors with machine learning to create a controller that is easier to manipulate than traditional models and could help people with limited fine-motor skills ...
