In this article we will learn how to make RPM Counter Using Arduino UNO.
In the last post we will learn how to make Trellis Shield Latching Keyboard test circuit in proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

 

 

Components:

1. Arduino UNO
2. LCD display
3. I2C module
4. Speed sensor
5. Jumper wires

Construction…

• Connect SDA pin of I2C module with A5 pin of Arduino UNO
• Connect SCL pin of I2C module with A4 pin of Arduino UNO
• Connect VCC pin of I2C module with VCC pin of Arduino UNO
• Connect GND pin of I2C module with GND pin of Arduino UNO
• Connect VCC pin of Speed sensor with VCC pin of Arduino UNO
• Connect GND pin of Speed sensor with GND pin of Arduino UNO
• Connect signal pin of Speed sensor with Digital pin 2 of Arduino UNO
• Dress up the wires clean and tidy

Working…                                                                                    

An RPM (Revolutions per Minute) counter, also known as a tachometer, It is a device that measures the rotational speed of a motor, engine, or any rotating object. You can build an RPM counter using an Arduino Uno and a few additional components
