درع متعدد الوظائف لـ Arduino Uno / Leonardo

It’s a solid little board for tinkering — the header pins line up perfectly with my Uno, and having the buzzer and LCD connection points already laid out saved me a ton of wiring guesswork. Setup took me about ten minutes as a total beginner, which felt pretty rewarding.

The 1602 LCD screen and buzzer make testing my Arduino sensor sketches so much easier without all the jumper wires. Having buttons and a joystick all on one board really streamlined my breadboard projects.

Plugged this into my Leonardo for a science fair project and the built-in buzzer saved me from having to wire a separate speaker. The screw terminal block makes connecting sensors way easier than fumbling with a breadboard. Just what I needed to get my display working quickly.
