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

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

The Arduino Uno Rev3 is the third revision of the classic Arduino Uno board. Compared to its earlier iterations, it includes upgraded components and new features, such as an ATmega16U2 instead of ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.

Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant re ...

Embedr is an AI-powered Arduino-like IDE designed to simplify development for Arduino-compatible microcontrollers. It looks ...

I did something similar with an Arduino Due, with a step stick to control the stepper motor for disks that had the donut come loose from the metal hub (3.5″ disks).

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...

We powered the sensor stick using the 5 volts out available on the Arduino Uno. I2C also requires pull-up resistors on the data (SDA) and clock (SCL) buses.

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
