This is the firmware for IU8NQI frequency counter board based on IMASAIGUY project (visit: https://www.pcbway.com/project/shareproject/Arduino_RF_Frequency_Counter_with_Prescaler.html)
This project is simple low-cost digital frequency meter using Arduino, SAB6456 IC Prescaler and some scrap components
originally created by IMASAIGUY
- Arduino Uno R3 (or Nano and compatible board)
- SAB6456 Prescaler Module (see schematics and pics for additional info)
- Arduino IDE
The source code is detaild commentated. Good Luck!
