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..
