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.

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

Raspberry Pi Music Player

Love Music? Or are too nerdy to make your own gadgets! (That was one of mine reasons. Duh!) Well, this is the Raspberry Pi Music Player. Watch the video below to find out what it is like Features: Control over bluetooth (smartphone) Commands can be given via voice (smartphone) Play Next Stop Increase Volume Decrease Volume First Song Date Time Shut Down LCD On LCD Off LCD Brightness Control Additional Info: I also installed Rune Audio on my other SD Card so that I could use it over my WiFi. But yes, that requires switching cards. But that makes it portable with a web interface. Currently facing problems with: Running without Ethernet plugged in on boot (worked perfectly fine with previous versions of Raspbian). Wanting to do this to make it portable. Repeat Functionality Shuffle Playing songs from USB And a few more bugs Write to me at sparkthatplug@gmail.com if you think you can help me with those problems. Innovative ideas are always
