PIC MCUs and other MCUs have analog to digital converter modules inside them. We will use PIC16F877A for this time.

Here are the required parts:

1- PIC16F877A or any PIC MCU.

2- Any 16x2 LCD.

3- Breadboard.

4- Breadboard wires.

5- Soldering station -> just to prepare the LCD itself with pins.

6- MPLAB X IDE from Microchip.

7- PICKit 3 or PICkit 4. now you are ready to start.
