To set the minimum level (0°C), place the diode in a glass of water filled with crushed ice (check the temperature first with a normal thermometer) wait until the thermometer shows zero degrees centigrade. Set P1 so that the digital voltmeter will display 000 when the diode senses zero d...
So to do it, power up the Voltmeter and the multimeter. Put the multimeter in Voltmeter range. Connect those two meter in parallel to a single power supply source. Check both the reading. Turn the potentiometer to either direction till the reading match to each other. Once done, now your ...
A simple 0-5V voltmeter using 8051.This digital voltmeter has a sensitivity of 200mV which is a bit low but this project is meant for demonstrating how an ADC and seven segment display can be interfaced to 8051 to obtain a digital readout of the input voltage. A 31/2 digit high end ...
