This is a simple frequency counter based on a microcontroller PIC16F84. The maximum working frequency is around 30MHz, and has a 10Hz resolution, with low current consumption (15mA), and very simple assembly. This uses 7 numbers seven segment LED display for displaying frequency The electrical schematic is very simple, given that most of the functions are implemented by microprocessor.
