An eForth for Arduino UNO/Nano implemented in C. .ino sketch file can be openned in Arduino IDE, no programmer to overwrite bootloader needed. Has 16-bit cells and stacks. Can read/write Arduino GPIO ...

The Arduino Uno is based on an ATmega328 microcontroller This board includes 14 digital I/O pins, a power jack, 6 analog input pins, a 16MHz ceramic resonator, a USB connection, a reset button, and an ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

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.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

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