Frequency Counter Do It Yourself Kit with LCD 10Hz - 250MHz
Full Package 10Hz - 250MHz with Green LCD and MB506 prescaler
Educational project for soldering!
The electrical circuit based on PIC16F628A microprocessor and 1/64 configured MB506 Prescaler. For better accuracy and stability, the MCU clocked by active 4.000MHz oscillator.
Prescaler block has about 50 ohm input impedance and two protection diodes for high frequency. MB506 divide input frequency by 64 and then trigger the MCU to count square wave signal. After the MCU complete count procedure, the processor will multiplies the number back by 64 to allow real frequency be displayed on LCD. In this way you can measure HF and VHF radio waves signals.
To measure signals under 10MHz, or audio frequency range, you can use "LF" input that drive input transistor amplifier stage directly. Be sure your signal has enough amplitude to trigger T2, usually its about 1V peak to peak signal.
LCD Module 16x2 Black on Yellow color is included! SMT mini USB socket is already soldered! All components are high quality!
MCU Software: Microcontroller program written in mikrobasic compiler. The kit has open source code for education purpose. Because the code size is less than 2K you can use Mikroe Demo Basic Compiler for PIC to modify the program. The code provided as is with no technical support for its modifications.
