Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor ...

This project presents an Arduino based speed monitoring system where the RPM (revolutions per minute) of a DC motor is continuously displayed on a smartphone using Bluetooth communication. The Arduino ...

I have put some Arduino PCBs to manufacture according to my protoboard. I have made a 12V to 5V converter and used transistors to transmitt signal. On RPM pins i put one pin to GND and the second one ...

A 3d printable motorised filter wheel. The wheel is motorised with a 28BYJ-48 stepper with control provided by an Arduino Nano. The firmware is compatible with Xagyl Indi and ASCOM drivers. I was in ...
