AVR Frequency Meter 40 MHz


This article shows how to build a small simple AVR frequency meter. The project is build on a veroboard, using only 3 components and 8 resistors. It is designed to be plugged into any standard bread-board. The design is built on a ATMEGA16 micro controller. There are no crystal oscillators, as we are using the internal RC oscillator, calibrated to 8 MHz. To programming the AVR microcontroller it used C code which is compiled with winAVR.
