Week 8: Make-through

• for it's not my first time I used raspberry pi many time but just for software level as a webserver or cluster computer and didn't used it with GPIO at all

Main Difference

first we need to confirm that GPIO pin Library is setup on raspberry pi it should be pre installed by default but if it's not working you can re install it again from terminal using apt-get

$ sudo apt-get update

$ sudo apt-get install python-rpi.gpio python3-rpi.gpio

Trial #1 (Successful): Connecting wires

First we need to understand the pinout of RPI

it have 5V ,3.3V , GND and other GPIO PINs

it also have 2 mode for indexing pins (BCM or Board Number)

you need to define this index on you code

after that you need to define pin for led and push button

and setup button to use built-in pull up restestance

then we create while true loop that act as void loop in arduino

and check if button state is 1 turn on le els turn of led
