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 ...

Push button, ground out pin ... A bunch of hot glue fixes this. The LCD is secured similarly. I generally power my Arduino projects from a shield. It lets me avoid wasting power through the ...

Control is via an Arduino Nano, with a few push buttons and a 16 x 2 LCD display for user feedback. Often, completing a first build will reveal all manner of limitations and drawbacks of a design.

This typically includes resistors, push buttons, and sensors ... are components that receive data from the Arduino. This includes LEDs, LCD modules, servo motors, and buzzers.

This is an Arduino project called 'Simon Says'. It is essentially a memory game with LEDs and push buttons. The Arduino will play us a sequence of LEDs and the user will try to recreate this pattern ...
