What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

Also, if you want to measure the speed of a moving object you can check out Arduino speed sensor tutorial where we have used two IR sensor and Arduino to measure speed of moving objects like cars.

Install the library in the Arduino IDE in the menu Sketch > Include Library > Add .ZIP library. Include it in your sketch. With the library installed in the Arduino IDE, you can include it from the ...

Overview : This projecr implements a car speed detector using an Arduino microcontroller and an IR sensor. The system measures the speed of passing evhicles by detecting interruptions in the infrared ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
