After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control ...
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 ...
Many households notice a small red light blinking on their digital electricity meter and often assume it signals a fault or unusually high billing. In reality, this tiny indicator is a built-in ...
Red light therapy uses specific wavelengths of light to enhance cell function and promote rejuvenation, with potential benefits for skin, inflammation, and pain. While generally considered safe, red ...
A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...
This project is a hardware-based communication system designed to assist speech-impaired individuals in expressing their basic needs using hand gestures. The system uses IR (Infrared) sensors to ...
