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 ...

Additionally, the Uno features two extra pins, a duplicate of the A4 and A5 pins (meaning, they're internally connected), that you can dedicate for I2C/TWI communication.

If you treat the pins as binary, you can read them as 00, 01, 10, or 11 (sequence the encoder outputs while spinning clockwise is 00, 01, 11, 10). If you have a reading of 01, the next reading can ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

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

Getting Started with Arduino, by Massimo Banzi, offers an accessible introduction. The platform's official website is a good source of tutorials, help, project ideas, and interaction with other users.

OMC's H19 fiber-optic shield has been adapted as a stackable add-on for the Arduino Uno. It’s designed to simplify the integration of fiber-optic data links into microprocessor-based platforms.

The Arduino 101 has the same dimensions as the Arduino Uno, and the pins are compatible. You can stick shields designed for the Uno on the 101. While the optimum voltage for the 101 is 3.3v, the ...
