Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

PIC, AVR, and Arduino are ubiquitous in projects these ... Instead of going with a microcontroller he built the circuit around a 555 timer. What he really needed in this case is a flip-flop ...

It is essentially a memory game with LEDs and push buttons. The Arduino will play us a sequence of LEDs and ... This project will incorporate simple circuit design and functional programming ...

[Ed] was tasked with adding push-button degaussing to an arcade ... decoupling cap to power the new deguassing circuit and connected the SSR to the Arduino as an open collector input.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
