This Arduino project implements a servo motor control system using three IR sensors for directional movement detection. The system monitors obstacles or movements in three directions (left, center, ...

Abstract— This report is about to an electronic hardware-based project where we have implemented an Arduino-based Smart Cricket Stadium. Our aim is to make cricket games more efficient during unstable ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

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 ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

サーボモーターを動かしたいとき、ライブラリを使用すれば簡単にそれが実現するが、ライブラリである以上何かしらの制約が存在する。例えば、Arduino UNOではピン9と10のPWMが無効となってしまう。また、他のライブラリとの競合が発生してしまうかもしれ ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
