This project involves designing and constructing a digital tachometer using an Arduino Nano. The tachometer measures the rotational speed of a motor or any rotating object and displays the RPM ...

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 Firmware: This code is uploaded to the Arduino Nano using the Arduino IDE. It reads data from the Hall sensor and calculates the RPM or time between pulses. Configuration options are available ...

Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

Four new Nano boards join Arduino's lineup. ... 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.
