Introduction: LED Chaser Using Raspberry Pi

About: Technology enthusiastic, crazy about embedded system, love Arduino and raspberry pi.

Hello everyone

Today I will make a LED chaser using raspberry pi.

Step 1: Things That Are Required

1) Raspberry pi

2) 10x LED's

3) Breadboard

4) Jumper wires

Step 2: GPIO Pins

Before beginning lets get some idea about GPIO pins in raspberry pi.

GPIO stands for General-Purpose Input/Output. These pins are a physical interface between the Raspberry pi and the outside world.

There are 40 pins on the Raspberry pi (26 pins on previous models), and they provide various different functions.

Step 3: Circuit Diagram

Step 4: Python Code

I have used nano editor to write the code.

$ nano

write the code then press ctrl + x and save the code.

Run the code using

$ python3

To stop the execution

ctrl + c
