HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

The sensor sends “hit” signals to a small Arduino Uno via a PC817 optocoupler. The headcount is then displayed on a small LCD screen positioned above the speed bag, allowing you to keep track ...

Once you have all your components, you can start assembling your high-speed camera trigger. Connect the piezoelectric sensor to the Arduino, and then connect the Arduino to the camera and flash.

Comimark 4PCS Tilt Sensor Module Vibration Sensor for Arduino STM32 AVR Raspberry Pi Intelligent car speed sensor counter module motor testing slot type optocoupler module, pack of 10 ...

This project used the XBee Pro Module to transmit and receive signals wirelessly, and an Arduino UNO executed all given instructions. The presence of the car was identified by an infrared sensor, also ...

Servo.h: For rotating the servo motor. NewPing.h: For interfacing with the ultrasonic sensor. Logic and Functionality The ultrasonic sensor measures the distance to obstacles. The Arduino processes ...

This library could be paired with a weather station device to provide wind speed and direction information, or it may be paired with a microcontroller operated wind turbine to seek prevailing wind ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed photography setup using one, instead of ...
