Summary of MULTI-VOLTAGE METER WITH PIC18F2550 PICBASIC PRO

This article describes a multi-voltage DC meter project using PIC18F2550 or PIC18F4455 microcontrollers with PicBasic Pro software. It measures 5V, 9V, and 12V DC (up to 30V) using voltage dividers for higher ranges, the onboard A/D converter without external references, and displays results on a 4-line LCD in 4-bit mode.

Parts used in the Multi-Voltage Meter:

PIC18F2550 or PIC18F4455 Microcontroller
LCD Display (4-line character display)
Voltage Divider Resistors
Xtal (Crystal Oscillator)
Onboard A/D Converter

Measuring DC voltage in the range from 30VDC 0VDC

PIC18F2550 VOLTAGE MONITOR CIRCUIT

To measure the voltages higher then the VCC (supply voltage of the ?C) i was thinking of using the well-known and simple voltage divider using resistors. Discover the possibilities of measuring DC voltages in a range from 0VDC to 30VDC. Use the Onboard A/D converter from the PIC18F4455 or PIC18F2550 range. Measure different DC voltages at a time. Try to do the measurement without using an external ref voltage.

– Measure: 5V DC
– Measure: 9V DC
– Measure: 12V DC
– Use Xtal
– Display the voltages on an 4-line char display in 4-bit mode
