ATtiny2313 Frequency Meter

April 04, 2013 By: admin Category: AVR, Display, Measurement, Project No Comments →

The project shows you how to build simple and powerful frequency meter using ATtiny2313 microcontroller. The frequency meter can be used to measure frequencies from 1Hz to 10MHz (9,999,999 Hz) with a resolution of 1 Hz over the entire range. It displays result on seven 7-segment LED displays. The project uses 22.1184MHz overclocking crystal to […]

AVR Wide Range LC,F, ESR Meter

LCFesR meter is a precise, wide range meter that can measure inductivity (L), capacity (C), frequency (F) and equivalent series resistance of a capacitor in-circuit (ESR) based on AVR ATMega88PA-PU microcontroller. It can be easily built with homemade one or double-faced PCB and available electronic components. dr. Le Hung, project designer, explained that measurement of […]

1 GHz Frequency Counter

May 01, 2012 By: admin Category: Digital, Measurement, PIC, Project No Comments →

This simple counter is built based on PIC16F84A and SAB6456 IC. The SAB6456 is a prescaler for UHF/VHF tuners. It can be switched to divide-by-64 or divide-by-256 by the mode-control (MC) pin. The circuit has an input frequency range of 70 MHz to 1 GHz, has high input sensitivity and good harmonic suppression. This project […]

PC Oscilloscope and Signal Generator
