Arduino Frequency Meter w/ LCD

(Using Platform IO and VS-Code)

  • A simple frequency meter designed using Arduino Nano (atmega328p).
  • Can measure frequencies upto 2.6 MHz of other Arduinos( running at 16MHz).
  • Uses two timers TC1 and TC2 for measuring the frequencies with a loop() sample frequency up to 1000 Hz.
  • Displays the Output on a LCD connected via a i2c Serial to parallel converter module.
  • LCD i2c address : 0x27 .
  • Uses code referenced from : Nick Gammons's Timer/Counter examples..
