How to Make Arduino Based Digital Tachometer Simple DIY Tutorial

 

 

Working principle :-

IR Sensor get penetrate by motion of motor shaft, signal are transfer from IR Senor module to Arduino.

This signal are processed in Arduino according to code loaded on it.

Then Arduino transfer signals to LCD Screen to display RPM

Step 4: Procedure


Bring a Zero PCB, Mount female header pin on PCB

Place arduino and LCD Screen on PCB

Make solder connection where it is required,

refer electrical drawing for better understanding.

place IR Senor module on PCB in way that its sensor face toward the

wheel of motor to whom RPM have to measure.

Connect the Arduino with PC to upload code.

Then connect the 9V battery to power up arduino & LCD 16 X 2 screen

you can adjust the brightness of screen by rotating that Knob connected at VEE of LCD Screen

 

Step 5: Arduino Code

Arduino Code
Click here to download Arduino code

upload the code to Arduino

Be sure you have selected right Board & port to successfully upload the code

Now you are ready to take RPM reading.

Manually rotate the Wheel of motor you can see RPM Reading are appear on screen

    When I originally commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I get four emails with the same comment. Is there any way you can remove people from that service? Bless you!
