Introduction
--------------------------
Hello friends, hope you all are fine and having good life. In today's project, we will see how to display ADC value on LCD using Arduino in Proteus ISIS. Its quite a simple project in which we are gonna measure the voltage of ADC pins and then will display them over to LCD.
The simulation is designed in Proteus ISIS.Arduino has 10 bit ADC pins so whenever you apply voltage on these pins it will give you a value ranging from 0 to 1023 depending on the voltage provided. One can easily get this value using a simple function in Arduino analogRead(); but the real problem is to convert this analog value into the actual voltage present on the pin. Suppose you are using A0 pin of arduino and you are providing 3.3V over to this pin, now when you use this analoagRead() function then it will give you some value say 543, but you wanna know what's the actual voltage at this pin which is 3.3V so now converting this 543 to 3.3 is a bit tricky part. It's not difficult but involves a little calculations, which I am gonna cover today in detail.

Display ADC value on LCD
--------------------------
The code is quite simple and self explanatory, the only difficulty is in ShowVoltage function. In this function, I have first taken an average of 10 ADC values and after that I have applied a simple formula over it and then it will start start giving the voltage value which I have simply displayed over the LCD.
Now everything's done, so Get your Hex File from Arduino Software and let's check the results whether it displayed ADC value on LCD using Arduino or not
Now if you compare the voltages in voltmeter and on LCD, you can see they are exactly the same. You can check the value of variable resistor and the values in LCD will also change as the voltage in voltmeter change.
