Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Alessandro also addresses the durability of the Uno R4, with protection diodes to prevent damage from common user mistakes. The new features, such as the switch to a USB-C connector and the option to ...

Simulating the Function of Logic Gates With Arduino Uno R3 This project is a digital simulation of logic gates using an Arduino. It allows users to experiment with fundamental logic operations, such ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

Abstract:A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of ...
