Want to make cool LED throwies at home, don't worry a bit here is a simple and elaborate tutorial on how to make one. This project applies the basic principle of diode and you can learn how to connect a LED to a power supply. This blog is dedicated to everyone from little boys who would like to make a cool gizmo to providing ideas and complex schematics for engineers. This is the first project so i'm sticking with the simplest of LED application. So, lets start.
First of all we would make a list of the parts needed to complete the project::
1) Several LEDs of different colours.
2) Some adhesive tape / blacktape (used for binding electrical components together).
3) 3.7 V / 3 V lithium ion batteries or button cell batteries.
4) Several small ( button ) magnets.
Here i'm going to provide images and schematics so that one can understand the working procedure, parts needed and the construction part:

Construction:
I'm going to put this in as simple language as possible.
A 3 volt LED is actually a Light Emitting Diode so it uses DC voltage and 1mA - 50mA ( milliampere) current and have the same properties of a Diode so it must be connected anode (positive) to anode and cathode (negative) to cathode with the DC supply (here 3 V battery)
The connection schematic is given in (figure 2) for easy understanding of the connection.
Now once you have connected the LED to a battery, it will glow and now just wrap them together with electrical tape now put a button magnet over the wrapped circuit and again wrap it with another piece of tape. Now you own LED throwie is ready to be deployed.
After completion it would look somewhat like the pictures below:

Here is a video for you:
So enjoy this LED project, I will be back with more whenever I get time to write them down.
