RPi Digital Input

Digital Input that means; feed digital data to uC or uP, In our case RPi take the digital I/P  by help of GPIO pin(General purpose Input Output pin) for example pushbutton, keypad,  

In Digital language we have two things that is ‘0’ n ‘1’; ‘0’ means GND(LOW) and ‘1’ means 5v or 3.3v(HIGH).

So those devices/sensors output like either 0 (GND/LOW) or 1 (5v/HIGH) we can say these are Digital Input devices; Don’t be confused Sensor’s output means it is input for uC(Micro controller)/uP(Micro Processor).

INSTALL DEPENDENCY:

• Check any Python package installed in RPi
• Open terminal paste below code

python

python3

• If python, python3 and GPIO library of python is Not installed copy the below code and paste in terminal.

sudo apt-get update
