This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are ... uses an Infrared beam to measure fan speed. As with last year’s PIC-based ...

If your daily driver was born without a tach, fear not – a simple Arduino tachometer is well ... The project is sensing engine speed using the coil trigger signal – a signal sent from the ...

Why not create your very own high-speed camera trigger using an Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera, and an external flash. Watch the video after the break to see it ...

Engineers often want to monitor a shaft’s rotational speed ... The sensor can also survive harsh environments and is not affected by accumulated dust, grime, dirt, and oil. The tachometer ...
