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, ...

Arduinoを使った電子工作で人気の「自動制御」。今回は、安価で入手しやすい「超音波距離センサー（HC-SR04）」と「サーボモーター」を使い、前方の障害物を検知して自動でハンドル（舵）を切る、障害物回避システムの作り方をステップバイステップでご ...

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 ...

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 ...

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 ...

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 ...

This code helps to control a servo motor using a touch sensor. You can connect the wires as below. Connect the touch sensor pin to D2 Connect the servo motor pin to D9 //below is the arduino code ...
