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

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 ...

Ever wanted to track your bike, car, or even monitor your loved one's location in real-time? Building your own Arduino GPS tracker gives you complete control over your tracking data without expensive ...

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.

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 ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

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 ...
