Digital voltmeter with PIC16F877A using Proteus and Micro C 

Great job

Good day Engineer Brandon. I built the same circuit and it simulates perfectly except that it seems that it cannot display voltages below 1V properly. For example 0.1V will be displayed as 1V, 0.01 will also be displayed as 1V. I did some digging and realised that the floattostr function is the cause. The sprintf function is a solution but the 16F877A does not support this function. How would you solve this problem. I see even in your video, you don't go below 1V

Can you help me here, can you display LM35 temperature sensor values on the LCD using AT89C51 microcontroller? LM35 must be connected to ADC0831. Can you do that conversion it is a challenge to me

👍👍👍

Hi your link to download the stuff does not work.

Awesome explaining but your voice is very low please improve rest of that all goood

how to save in hex file ya

Can it measure ac voltage ?

I'm not being able to find res1 register
