The frequency meter can be used to measure the frequency of 10 Hz-60Mhz. The frequency meter has a level of precision or resolution of 10Hz. The frequency meter can be used to measure the frequency of the oscillator, transmitter, frequency generator, cristal, and others during the working frequency trsebut devices in the range 10 Hz - 60MHz. Circuit frequency meter using PIC 16F628A dibagun and with the viewer of the LCD 16 × 2. Frequency meter circuit is working with the working frequency of 4MHz crystal. The series is an electronic frequency meter is quite simple to make. The following picture of the frequency meter circuit.
The series of frequency meters above basically works with the source voltage 5VDC. In this series of 7805 voltage regulator has been installed, so it can be operated with a voltage of 5 - 15VDC.
PIC Volt and Amere Meter Circuits
Volt meter and ampere meter with PIC can be used to measure voltage and current at the same time. The series of volt meter and ampere meter with PIC uses a PIC16F876A as a data processor voltage and current are measured. This circuit uses a LCD viewer 16 × 2, which is used for displaying data voltage and current measurements. In the article volt meter and ampere meter with PIC is to be discussed is limited to devices faucet only. For more details can be seen from the image sequence volt meter and ampere meter with PIC below.
In the circuit volt meter and ampere meter with PIC above used 3 pieces of buttons for setting Calibration measurement data. The circuit is basically working with the source voltage 5VDC.
