Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec. Here we design a simple non-contact tachometer using microcontroller, ...

This tachometer is based on Atmel ATmega8L microcontroller and Nokia 5110 LCD LPH7366 for measuring rotation speed of any rotating things. A photo sensor is functioned by a photoresistor that is used ...

We know that the rated rotational speed of an industrial motor is based on two fixed factors: the number of poles and the supply frequency. So if you install a 4-pole, 480V motor in a 480V, 60Hz ...

When the Mustang came out in 1965 (or 1964½, whichever you happen to consider the first Mustang), one of the optional accessories was a Rally-Pac that mounted a tachometer and clock on either side of ...
