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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Matt Carey, the co-founder and CEO of Boston-based startup Teradar, loves when people tell him: “I don’t believe you.” That’s “right where we want folks,” he recently told TechCrunch. Carey has spent ...

Real flowers do it, and even the Beatles did it. [Robo Hub] now has a plastic sunflower that tracks the sun using, of course, an Arduino. It may not qualify as a real robot, but it does mimic a real ...

Abstract: The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing ...

An 8-sensor LDR line following robot using ESP32 with dual-threshold hysteresis algorithm. The project includes both Arduino IDE and ESP-IDF development environments, plus threshold calibration tools.

While Lana Del Rey’s upcoming album The Right Person Will Stay may not be the pure country project she teased back in February, it does apparently feature one of Nashville’s most successful ...

You never forget your first diorama, especially when it’s interactive. Although admittely a bit late to celebrate Erntedankfest (Germanic Thanksgiving), [Markus ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
