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 ...

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, ...

For decades, the gauge cluster of a German car was a thing of functional beauty. Clean design placed an emphasis on legibility above all else. In recent years, however, the rise of LCD screens ...
