How to Make Graphical Digital Lock with Raspberry Pi & Python

In this tutorial, we are going to make a digital lock with a graphical user interface library in Python (Tkinter). Input data is 10-bit adc ( 0~1023) which comes from potentiometers and is transmitted to Raspberry Pi by Raspberry Pi Pico. Raspberry Pi 3 receives the data from UART, decodes them, and compares them with the password. If the given password matches, it turns on the relay.
