Description: This Arduino project integrates an NFC reader, a servo motor, and LEDs to create a simple access control system. The system operates as follows: When a specific NFC card is detected, the ...

サーボモーターの角度はPWMで制御します。 PMW Period: パルス信号の周期(SG90の場合1秒間に50Hz) この周期の中でHIGHにしている時間を見てサーボモータの角度を調整しています。 Duty Cycle: 周期的な現象において、"ある期間" に占める "その期間で現象が継続さ ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

Arduinoでサーボモーターを動かす基本をマスターしたら、次はもっと複雑な動きに挑戦してみたくなりますよね。今回は、そのステップアップとして、2つの車輪を回すDCモーターと、距離を測る超音波センサーを組み合わせ、前方の障害物に自動でついていく ...

While building robotics projects, the importance of controllers and motors cannot be overstated. These components are the heart and soul of any robotic system, providing the necessary control and ...

If one could temporarily remove their sense of humor and cast a serious look into a Rube Goldberg machine, they would not say to themselves “well that looks simple.” Indeed, it would almost always be ...

This could be an interesting one if you work with robotics, flagged by the Arduino team - a look at how to smooth the operation of a servo, to avoid jerking between positions. It's from the YouTuber ...
