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 ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

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 ...

Circuit Diagram. Circuit diagram for this Arduino based 230v fan speed control circuit is given below:. Note: I have shown the complete circuit on a breadboard only for the purpose of ...

The project concentrates on triggering a flash of camera by using sensors such as microphone or laser pointer to produce a high speed photography. There are big benefits that the Arduino ...

This is a work in progress. More content in this Readme, especially about calibration Ability to measure cameras like Barnack Leicas where you cannot access the rear of the shutter curtain. Finish ...

Fig. 1: Circuit diagram of the temperature-based fan speed control and monitoring using Arduino The circuit diagram of the temperature fan speed control and monitoring is shown in Fig. 1. It is built ...

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 ...
