FC-33 (LM393) infrared speed sensor is used to measure the RPM of the motor. In addition, we can increase or decrease the speed by controlling the speed of the motor with the potentiometer used in the ...

README RPM Sensor with Arduino This repository has some files related to this tutorial on creating a revolutions per minute (RPM) sensor using an Arduino board. You can find the code used in ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...

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 ...

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 ...

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.

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 ...

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 ...
