How to Play Bulleya on guitar Ae Dil Hai Mushkil

Bulleya - Aey Dil Hai Mushkil - Guitar Chords & Lyrics



Bulleya

Dminor.....................Cmajor........
Meri rooh ka parinda phadphadaye

Dminor.....................Cmajor........
Lekin sukoon ka jazeera mil na paaye

B#maj............
Ve ki karaan..

AMajor....
Ve ki karaan..

Dminor..................Cmajor...
Ik baar ko tajalli toh dikha de



Dminor..................Cmajor...
Jhoothi sahi magar tasalli to dila de

B#maj............
Ve ki karaan..

AMajor....
Ve ki karaan..

Dminor...........................
Raanjhan de yaar Bulleya

B#major.............
Sunle pukaar Bulleya

Cmajor....................
Tu hi toh yaar Bulleya

B#major...........Cmajor.........
Murshid mera, Murshid mera

Dminor............
Tera mukaam kamle

B#Major.................
Sarhad ke paar Bulleya

Cmajor....................
Parvardigar Bulleya

B#Major.................Cmajor....................
Haafiz tera, Murshid mera (x2)


Dminor..........................................Cmajor........
Main taan gul se lipti titli ki tarah muhajir hoon


B#Major.................Cmajor....................
Ek pal ko thehroon, pal mein udd jaaun


Dminor...............................
Ve main tan hoon pagdandi

.........................Cmajor.....
labhdi ae jo raah jannat ki

B#major.........................Cmajor...
Tu mude jahan main saath mud jaaun

Dminor.............................Cmajor......
Tere kaarvan mein shamil hona chahun

Kamiya taraash ke main kaabil hona chahun
Ve ki karaan..
Ve ki karaan..

Raanjhan de yaar Bulleya
Sun le pukaar Bulleya
Tu hi toh yaar Bulleya
Murshid mera, Murshid mera
Tera mukaam kamle
Sarhad ke paar Bulleya
Parvardigar Bulleya
Haafiz tera, Murshid mera (x2)

Raanjhana ve…
Raanjhana ve…

Jis din se aashna se do ajnabi huve hain
Tanhaiyon ke lamhe sab multavi huve hain
Kyun aaj main mohabbat
Phir ek baar karna chahun
Haan…

Ye dil toh dhoondhta hai inkaar ke bahane
Lekin ye jism koi pabandiyan na maane
Milke tujhe, bagaawat khud se hi yaar karna chahun

Mujhme agan hai baaki aazma le
Le kar rahi hoon khud ko main tere hawale
Ve Raanjhna…
Ve Raanjhna…

Raanjhan de yaar Bulleya
Sunle pukaar Bulleya
Tu hi toh yaar Bulleya
Murshid mera, Murshid mera
Tera mukaam kamle
Sarhad ke paar Bulleya
Parvardigar Bulleya
Haafiz tera, Murshid mera (x2)

Murshid mera, murshid mera

Arduino Traffic Light Controller

The use of personal vehicles is very common now a days and a result, the number of vehicles on the roads are exponentially increasing. Roads without any supervision or guidance can lead in to traffic congestions and accidents.
Traffic Lights or Traffic Signals are signaling devices that are used to control the flow of traffic. Generally, they are positioned at junctions, intersections, ‘X’ roads, pedestrian crossings etc. and alternate the priority of who has to wait and who has to go.
The traffic lights will provide instructions to the users (drivers and pedestrians) by displaying lights of standard color. The three colors used in traffic lights are Red, Yellow and Green.
The system must be used to control the traffic lights for smooth and safe movement of traffic. These control systems consists of electro mechanical controllers with clockwork mechanisms or modern solid state computerized systems with easy setup and maintenance.
In this project, an Arduino based Traffic Light Controller system is designed. It is a simple implementation of traffic lights system but can be extended to a real time system with programmable timings, pedestrian lighting etc.

Circuit Diagram



Components

  • Arduino UNO
  • 1KΩ Resistor X 12
  • Red LEDs X 4
  • Yellow LEDs X 4
  • Green LEDs X 4
  • Connecting wires
  • Prototyping board
  • Power adapter

Component Description

Arduino UNO: The main part of the Traffic Light Controller is the controller itself. Arduino UNO will serve the purpose in this project to handle all the switching of the LEDs and controlling their timings.
LEDs: The LEDs used in the project are basic 5mm LEDs of Red, Yellow and Green colors. The maximum current that can be allowed through these LEDs (Red, Yellow and Green in particular) is 20mA. (Foe Blue LED, the maximum current can be up to 30mA).

Circuit Design



Since the project is a traffic light controller, the circuit consists of many LEDs (12 as a matter of fact) as we are implementing traffic lights at a 4 way intersection. The project is a simple representation of traffic light controller and hence no other extra components are used.
We need three LEDs of Red, Yellow and Green colors at each intersection. The intersection is divided in to four lanes: Lane1, Lane 2 Lane 3 and Lane 4.
All the LEDs are connected to the Arduino UNO’s digital I/O pins through respective current limiting resistors of 1KΩ.
All the connections are made as per the circuit diagram. The complete wiring diagram of the circuit is shown below.
Note: In the practical implementation of the project, we did not use the current limiting resistors as the current from each digital I/O pin of the Arduino UNO is only 20mA. This small current will not burn the LED. But it is advised to use the current limiting resistors of at least 220 Ω in series with each LED.
Also note that Arduino UNO in this project acts as source of current for all the LED i.e. it provides the necessary current to turn ON the LED. Hence, a reliable power supply (like a DC adapter) to power the Arduino UNO must be used.

Working of the Traffic Light Controller Project

The real time traffic light controller is a complex piece of equipment which consists of power cabinet, main controller or processor, relays, control panel with switches or keys, communication ports etc.
In this project, a simple traffic light system for a 4 way intersection is implemented using Arduino UNO. Although it is not the ideal implementation for real life scenarios, it gives an idea of the process behind the traffic light control system
The aim of the project is to implement a simple traffic light controller using Arduino UNO, where the traffic is controlled in a pre-defined timing system. The working of the project is very simple and is explained below.
Consider the following gif image showing a loop of traffic light operations. The project is also implemented in the same manner.

In that, first the Lane 1 gets its Green light turned. Hence, in all the other Lanes, their corresponding Red lights are turned on. After a time delay of predefined time say 5 seconds, the Green light in the Lane 3 must be turned on and the Green light in the Lane 1 must be turned off.
As a warning indicator, the Yellow light in Lane 1 is tuned on indicating that the red light is about to light up. Similarly, the yellow light in the Lane 3 is also turned as an indication that the green light about to be turned on.
The yellow lights in Lanes 1 and 3 are turned for a small duration say 2 seconds after with the red light in the Lane 1 is turned on and green light in Lane 3 is also turned on.
The green light in Lane 3 is also turned on for a predefined time and the process moves forward to Lane 4 and finally Lane 2.
The system then loops back to Lane 1 where the process mentioned above will be repeated all over again.
Note: The project implemented here doesn’t include the pedestrian crossing and pedestrian signaling in to consideration.

Limitations

  • The project is not suitable for actual implementation but just a demonstration of the process behind the system.
  • Real time traffic light controller systems are generally run time programmable i.e. the operator (usually a policeman) can change the timings of each lane as per the intensity of the traffic in each lane.
  • There will also be a provision for either manual operation or pre-programmed operation.

Applications

  • A simple traffic light controller is implemented in this project with a real chance of expansion.
  • An external memory can be interface with the main controller so that the timings are not fixed during its programming but rather can be programmed during operation.
  • An efficient traffic light controller system will include a pedestrian signaling system
