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.

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like [Electr… ...

Let's create a simple project where two Arduino Uno R3 boards communicate wirelessly using the nRF24L01 modules. One Arduino will act as the transmitter, sending data to the other Arduino, which will ...

This Arduino project provides a simple menu system for controlling the brightness of LEDs using button inputs. It utilizes an Arduino Uno and a keypad shield for user interaction. Relevant information ...

While over 10 million users have enjoyed playing and working with Arduino UNO R3’s 8-bit microcontroller for more than a decade, the new RA4-series MCU will open up endless new project ...

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

Previously we have done a comprehensive comparison between the Arduino Uno R3 and Arduino Uno R4 with the main focus on the hardware specifications and features of each board. In this article, we will ...

The Arduino UNO R4, featuring the Renesas RA4M1 (Arm Cortex-M4) running at 48MHz, boasts a 3x performance increase over the UNO R3. Additionally, SRAM has been upgraded from 2kB to 32kB, and flash ...
