Python Code 1.1.1 Blink
Net, we will use Python language to make LED blink.
First, observe the project result, and then analyze the code.
1.
Use cd command to enter 01.1.1_Blink directory of Python code.
cd ~/Freenove_Ultimate_Starter_Kit_for_Raspberry_Pi/Code/Python_Code/01.1.1_Blink
2. Use python command to execute python code blink.py.
python Blink.py
Now, LED start blinking.
You can press “Ctrl+C” to end the program. The following is the program code:

In subfunction setup(), GPIO.setmode (GPIO.BOARD) is used to set the serial number for GPIO based on
physical location of the pin. GPIO17 use pin 11 of the board, so define ledPin as 11 and set ledPin to output
