RPM Sensor with Arduino This repository has some files related to this tutorial on creating a revolutions per minute (RPM) sensor using an Arduino board. You can find the code used in rpm_sensor.ino , ...

This repository involves two different techniques implemented on Arduino IDE platform for calculating RPM(Revolutions per minute) of a spinning object RPMCounter(using Hall Effect Sensor):This ...

We start our arduino flex sensor code by defining the pins for the flex sensor and LED. Next, we define some variables where we have defined all the required parameters like VCC, the value of the ...

Pair the Bluetooth between the smartphone and HC-06. Open the Arduino Bluetooth Controller app from an Android phone and select Terminal Mode. Now switch on the motor. As the encoder disc rotates ...

In this Arduino LM393 speed sensor tutorial we will use the simple and easily available LM393 speed sensor module to measure some vital parameters like Speed, Distance travelled and Angle of the ...

I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...
