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, ...

Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...

This project circuit helps to detect and control the water level in an overhead tank or container. Here, we use 8051 microcontroller. This is an interesting and very useful project in our real life.
