Lighting A LED Using Raspberry Pi

Lights? Cool ha?
Lights are an easy way to express indications for any process, they are like little alerts or notifications.

Today, let's learn how to set up a LED with a Raspberry Pi.

You should already know how to log in via SSH and use Filezilla. If you don't know how to, then follow the links below:
SSH - click here
Filezilla - click here

To see the practical demonstration, watch the video below.


Things you'll need:
  • Raspberry Pi
  • Power source for Pi
  • A LED
  • Resistor (330 Ω)
  • Breadboard
  • Male to female jumper cables
Assemble your circuit as shown below:

Note: Make sure you connect the positive end of the LED to GPIO 21 and the negative end to Ground PIN

Now turn on your Raspberry Pi and copy the LED.py file to /home/pi/ using Filezilla
Download LED.py here

Now open terminal and type the following:
sudo python LED.py

Your LED should now blink 4 times with a delay of 2 seconds.

To exit the program press:
Ctrl+C

You can also edit the code if you feel like experimenting. Type:
sudo nano LED.py

Save your changes by pressing:
Ctrl + X, Y then press Enter

Have fun with your light set up and let me know about it in the comments!

Setting Up Your Raspberry Pi - SSH

Hello everyone! So, Raspberry Pi? Having problems setting up your little computer? I'm here for the rescue! Follow the procedure if you want to set up your Raspberry Pi through a SSH (Secure Shell) or as others call it the 'Headless method' and use Raspbian as your operating system. I would personally suggest to use Raspbian as your first operating system on the Raspberry Pi. Watch the video for better understanding. First of all, the hardware that you'll need is: Raspberry Pi (I own a Raspberry Pi Model 3B) Ethernet Cable SD Card or Micro SD Card depending on your model of Pi (I'll use a 8GB Micro SD card) Power Supply of ratings 5.1V and 2.5A max (I use my phone charger which has a rating of 5V and 2A) Laptop/desktop PC (I'll be using a Windows 10 laptop) Now coming to the software side: Latest image file of the Raspbian operating system. I'd recommend you to download Raspbian Jessie With Pixel because it has many addition...

Watch the video on how to share files: The sftp (SSH File Transfer Protocol) makes the whole process possible. To use it: Download and install FileZilla - download link  here Open FileZilla, in the top left corner enter your Pi's IP address in the Host column In username filed enter 'pi' In the password filed enter the password for your Pi Enter 22 in Port and hit Quickconnect You should now see files on your computer on the left and files on your Raspberry Pi on the right. Now you can access all the files like you do on a normal computer. You can download and upload files. It also has many other options like like making a file executable which is similar to the command chmod that we use in the terminal. FileZilla...
