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 ...

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They n… ...

Arduino Uno, Nano, Pro Mini, Mega, ... For that, we are going to use the MFRC522 Arduino Library by Miguel André Balboa. Since the library is not available in the Arduino library manager, download it ...

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...

Connections between Arduino and RFID are given in the table below. The positive pin of the buzzer is connected to digital pin 4 of Arduino, and the GND pin is connected to the ground pin of Arduino. A ...
