Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

However, the only Arduino platform included is an Uno R3. You can still create different circuits with this board, though, especially if you're primarily working on beginner projects.

Step into the world of innovation with the Arduino Starter Kit Uno R3 by Elegoo. This kit provides everything needed to bring creative projects to life, from beginner experiments to advanced builds.

Keeping the pinout, voltage and form factor unchanged from the UNO R3 ensures maximum hardware and electrical compatibility with existing shields and projects while allowing the UNO R4 boards to ...

The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance Stage.

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.

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