Here we are going to design an Arduino based digital tachometer using IR sensor module to detect object for count rotation of any rotating body. As IR transmits IR rays which reflect back to IR ...

This project aims to create a cost-effective and efficient digital tachometer using Arduino Nano and an IR sensor. The tachometer will provide real-time feedback on the rotational speed of motors, ...

This tutorial will guide you through the process of building a tachometer around an Arduino ... an Infrared beam to measure fan speed. As with last year’s PIC-based tutorial, [Chris] is using ...

The QRD 114 IR (optical) proximity sensor ... to drive the LED of the optical sensor. int sensorPin = 0; // use analog in pin A0 pin 0 to read the PD of the optical sensor int previousValue; // ...

There are various types of tachometers. Described here is a digital non-contact type tachometer using a proximity sensor. The circuit diagram of the Arduino-based tachometer is shown in Fig. 1. It is ...

In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure ...
