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 ...

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

It's programmed using the Arduino IDE, so most of the sketches built into the software can be tested with the Nano. The board also operates at 5V, similar to most Arduino boards.

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

In this article we will review the Arduino Nano 33 BLE sense board, introduce you to its features and functionalities and finally write a sample code to read the sensor values and display on serial ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

The Raspberry Pi Pico is both faster and cheaper than the Arduino Nano, but the nano has better resources and community.
