Description

Description:

Tachometer is a simple module that allows you to test the speed of the motor.Widely used for motor speed detection, Pulse count, position limit, and so on.

Features

Puzzle interface
infrared photoelectric sensor
Working voltage 3.3v-5v
Output: digital switch output ( 0 and 1 )

Code:

#include <TimerOne.h>
unsigned int counter=0;
void blink()
{
counter++;

void timerIsr()

Timer1.detachInterrupt(); //disable the timer1
Serial.print("The speed of the motor: "); 
Serial.print(counter,DEC); 
Serial.println("round/s"); 
counter=0; 
Timer1.attachInterrupt( timerIsr ); //enable the timer1
}
void setup() 
{
Serial.begin(9600);
Timer1.initialize(1000000); // set a timer of length 1sec
attachInterrupt(0, blink, RISING); //INT0
Timer1.attachInterrupt( timerIsr ); // attach the service routine here

void loop()
{
; //do nothing
}
Tachometer modules can be connected to the relay to form features such as Limit switches, you can also connect to the active buzzer module, consisting of alarm.

Package Included:

1 X Tachometer Speed Module
