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, a circuit diagram in ...

Measures the RPM of a 3.3v signal on pin 12. Displays the result on an Adafruit i2c 16x2 LCD and also outputs it on the USB/serial connection in a format suitable for the Arduino IDE plotter tool.

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Arduino lends itself very well to a hands-on learning style, so pick up some basic equipment, work through a few tutorials, and then tackle some fun beginner projects. To get started, you will need: ...

Krejci’s design, while affordable, offers an 8×8 resolution, which is the maximum output of the AMG8833 infrared sensor array. DIY Arduino thermal camera Watch this video on YouTube .
