This project involves developing a simple application using an Arduino and an ultrasonic sensor to measure the speed of an object. The application will calculate the speed based on the time taken for ...

DAOKAI 5PCS LM393 Comparator Speed Sensor Module Slot Type IR Optocoupler for Motor Speed Detection Also for MCU Arduino, with Dupont Wire Comimark 4PCS Tilt Sensor Module Vibration Sensor for Arduino ...

Arduino Uno With Optocoupler Relay is a board based on ATmega328p which is an 8-bit microcontroller from ATMEL. The main purpose of building this board is to use it in COVID-19 and similar kinds of ...

The task of sensing dc current at high voltage is often problematic. Most high-side current-sensing ICs available off the shelf are good only to 30 or 40V. Combining an optocoupler with such an IC ...
