Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor.

In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

The Arduino Nano Every is faster, cheaper, and has more memory than it's predecessor, but what is it, and what can you use it for?

This was helped further thanks to the use of transistors to run the LEDs directly from battery voltage, rather than obeying the current limits of the Arduino Nano’s output pins.
