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.
PIC 16F88 based 4 digit Up Down counter circuit with explanation
This is a 4 digit decimal counter which can operate as a free running counter or in count and hold mode with manual reset. In either mode the counter can be preset to count to a specified value. Clock edge and leading zero suppression can also be configured. The 7-segment display and indicator LEDs are multiplexed. It will drive most common anode 7 segment LEDs. I used four single digit LEDs but a four digit LED module could also be used. In free running mode the overflow output resets on the next clock pulse. Therefore the pulse duration is directly related to the input clock frequency.
