RPM meter is very common problem in Embedded system development. Most of the time we need to measure RPM and for this we need some kind of RPM or Tachometer. The most common approach that is used for making Tachometer or RPM Meter is to measure pulses for a specif duration and then multiply it […]
In this post we are going to create a frequency meter using arduino. This frequency counter will count the number of cycles per second and will display the output on 16×2 LCD. We used proteous for simulation purpose and to quickly test our circuit. Full source code is provided at end of the post.
