In this tutorial we are going to build simple frequency meter (frequency counter) using ATmega16 and codevision avr compiler. This simple frequency meter (frequency counter) can measure frequency up to 4Mhz (theoretically) because we are using 8Mhz clock for the ATmega16 micro-controller. But you can use an external crystal oscillator of frequency 16Mhz and increase uo...
