WS2812B & Arduino. Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers. Now it is ...

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.

The core of this project is the Arduino Nano, a small, complete, and breadboard-friendly board based on the ATmega328. The Arduino Nano is programmed to control the frame’s components, which ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor ...

The electronics are straightforward, with the complete parts list consisting of an Arduino Nano 33 IoT device connected to a pair of RGB LEDs and 50 Ohm resistors.

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 ...

Finally, the Nano 33 BLE Sense is available for $29.50 and comes with a range of extra sensors to support wearable device and gesture-based projects. Otherwise it has the same basic tech specs as ...
