How to Make Party Lights by LEDs

What makes a party enjoyable??? Lighting system. It will give your party a new look. In this instructable you will learn 3 ways to light up your party. According to your party you can use different lightings. They all are very low budget and very easy to make. You can also combine your lighting systems. They all operate on a simple 9v battery.

The first circuit is very simple. Even a baby can do this. The things that you will need to make this circuit are

Some rgb LEDs(according to your need)
9v dc power source(9v battery)

It is made by joining rgb (red, green, blue) LEDs to a 9v battery. Connect 2 rgb LEDs in series and then connect them to a 9v battery. There is no need for schematics but I'm still giving one for the noobs(no offence).

The second circuit is made of flashing LEDs. It uses a 555 ic to blink the LEDs. You can use any color of LEDs of your choice. You can also mix LEDs of different colors. The things that you will need to make this circuit are

555 ic
1 k resistor
10 k resistor
10 uf capacitor
0.1 uf ceramic capacitor(104)
Some LEDs of any color
9v dc power source(9v battery)

This circuit puts the 555 ic in astable mode and it acts as a multivibrator and thus blinks the LEDs. It gives 9 volts so you will need to use 3 LEDs in series. The sets of 3 LEDs will need to be put in parallel. Fix these LEDs around the dance floor. The schematic is given in this step.

The third circuit is a very easy one. It doesn't need to be assembled on a pcb or perfboard. The things that you need to make this circuit are

Tip 31 transistor(most npn transistor work)
4 LEDs of any color
3.5mm pin
12v dc power source(12v battery)

If you want to use 9v battery then you will have to use 3 LEDs. Remember that 1 LED takes 3 volts so use your LEDs acvording to your power source. The circuit is given in this step. Please  tell me if you have doubts or some updates about this instructable.
