[Roni] programmed an Arduino Nano R4 to estimate Pi using the Monte Carlo method. For this specific case, it involves drawing a circle inscribed inside a square.

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

This results in undesirable coloration, which is why the color sensors from Micro-Epsilon maximize the quality of the products in this process through precise color measurement.

This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, green, and ...

Realizing full color GaN-based micro- and nano-light-emitting diode (nLED) displays with quantum dots (QDs) being the color conversion media remains challenging because of the limited QD color ...

🚀 Arduino Explorer: 30 Days, 30 Sensors – A daily hands-on journey exploring 30 different sensors with Arduino Nano. Each day includes code, wiring, diagrams & full explanations.

Arduino Library for the SparkFun Air Quality PM1/PM2.5/PM10 Sensor - BMV080 The SparkFun Air Quality PM1/PM2.5/PM10 Sensor - BMV080 (Qwiic) is an ultra-small, fan-less air quality sensor for sensing ...

Here, we present a four-color reservoir computing (RC) system based on an opposite photogating (OPG)-engineered multispectral photosynapse. The OPG effect, characterized by light-modulated oppositely ...

The necessity for achieving high-performance and precise detection of internal and external stimuli in physical and biological settings has emerged as exceedingly crucial in recent years. The ...
