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 ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

At embedded world, on the DigiKey booth, Lucy Barnard speaks with Marta Barbero at Arduino, about the new Arduino product announcement.

Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things ...

They go by names like “Alto,” “Irene,” and “Shoeshine,” but for years, outdoor, non-feral cats have largely been invisible inthe North Texas Dallas city code. Advocates for so-called “community cats” ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

Presidents' Day deals have brought the bundle down to a near record low. The best VPN deals: Up to 87 percent off ProtonVPN, Surfshark, ExpressVPN, NordVPN and more Top VPNs give out steep discounts ...

This program written with Arduino Code running on ESP8266 (Wemos D1) is just a test to access, read status and control Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) ...

Abstract: The chemiluminescent signal in lab-on-a-chip (LOC) is generally weak and also has a short lifetime, hence, a sensitive and fast detector is required for detection. Aiming for acquisition of ...

Abstract: The utilization of fluorescence detection for various biomedical applications such as oximeter sensors, cancer detection, monitoring of protein-DNA interactions, heart stroke detection, etc.
