The Tachometer library allows you to measure the rotational speed (RPM) using a tachometer sensor with an Arduino. It provides an easy interface to initialize the sensor, handle interrupts, and calculate RPM based on sensor pulses.

• Simple Initialization: Easy setup of the tachometer sensor pin.
• RPM Calculation: Accurate calculation of RPM with debounce handling.
• Customizable Revolutions: Configure the number of revolutions for averaging RPM calculations.

1. Manual Installation:

   • Download the Tachometer library files.
   • Place the Tachometer folder into your Arduino libraries directory, typically found at Documents/Arduino/libraries.

2. Using the Arduino IDE:

   • Go to Sketch > Include Library > Add .ZIP Library...
   • Select the .zip file containing the Tachometer library.

You can create only one instance

Here’s a simple example to get you started with the Tachometer library:

#include <Tachometer.h>

const uint16_t SENSOR_PIN = 2; // Replace with your sensor pin

Tachometer tachometer(SENSOR_PIN);

void setup() {
    Serial.begin(9600);
    if (!tachometer.init()) {
        Serial.println("Tachometer initialization failed!");
    }
}

void loop() {
    double rpm = tachometer.getRPM();
    Serial.print("RPM: ");
    Serial.println(rpm);
    delay(1000); // Update every second
}
