By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come up with a method ... the type and number of RFID cards required to trigger one of the Arduino’s digital pins, which ...

Apart from the Arduino UNO, the circuit consists of two more primal parts ... For example, I used the output signal of the proximity sensor to trigger my old wireless doorbell thru an optocoupler ...

For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino Leonardo, Micro or Pro Micro) Arduinos have hysteresis built into the input side of digital IO pins (as ...

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like ...

If you're on the hunt for the perfect board, then you've probably come across the Uno and Nano. They're two of the most frequently used Arduino variations, but they serve different purposes.

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed photography setup using one, instead of ...

The official Arduino team has this week revealed more details about the new Arduino UNO R4 development Board which will be officially launching in a few months time during May 2023. The ...
