CHORD GITAR AVENGED SEVENFOLD

Lyric and chords of Afterlife-A7X by Wiyat Gelo Sia

Easy Chords



Am F C G 4x

(*)

Am Em Am Em

Like walking into a dream, so unlike what you’ve seen

Am Em F G

So unsure but it seems, ’cause we’ve been waiting for you

Am Em Am Em

Fallen into this place, just giving you a small taste

Am Em F G F-G-F

Of your afterlife here so stay, you’ll be back here soon anyway



(#)

Am G F G

I see a distant light, but girl this can’t be right

Am G F

Such a surreal place to see so how did this come to be

G

Arrived too early



(@)

Am F

And when I think of all the places I just don’t belong

C F G

I’ve come to grips with life and realize this is going too far



Chorus 1 :

C G Am F C

I don’t belong here, we gotta move on dear escape from this afterlife

G Am F C

’Cause this time I’m right to move on and on, far away from here



(**)

A place of hope and no pain, perfect skies with no rain

Can leave this place but refrain, ’cause we’ve been waiting for you

Fallen into this place, just giving you a small taste

Of your afterlife here so stay, you’ll be back here soon anyway

(by Wiyat Gelo Sia)



(##)

This peace on earth’s not right (with my back against the wall)

No pain or sign of time (I’m much too young to fall)

So out of place don’t wanna stay, I feel wrong and that’s my sign

I’ve made up my mind



(@@)

Gave me your hand but realize I just wanna say goodbye

Please understand I have to leave and carry on my own life



Chorus 2 :

I don’t belong here, I gotta move on dear escape from this afterlife

’Cause this time I’m right to move on and on, far away from here

Got nothing against you and surely I’ll miss you

This place full of peace and light, and I’d hope you might

Take me back inside when the time is right

(by Wiyat Gelo Sia)



Music :

Am F C G 6x



Am F Dm

Loved ones back home all crying ’cause they’re already missing me

Am F Dm

I pray by the grace of God that there’s somebody listening

Am F Dm

Give me a chance to be that person I wanna be

(I am unbroken; I’m choking on this ecstasy)

Am F Dm

Oh Lord I’ll try so hard but you gotta let go of me

(Unbreak me, unchain me, I need another chance to live)



Music 2:

Am F C G 4x

C Dm Em F G



Chorus 3 :

I don’t belong here, I gotta move on dear escape from this afterlife

’Cause this time I’m right to move on and on, far away from here

Got nothing against you and surely I’ll miss you

This place full of peace and light, and I’d hope you might

Take me back inside when the time is right

Ayo!! buatlah robot line tracer

Line Tracer Program (Kitae Kim)





Fireworks Photo Caption
=================================================
Second, following picture is motor controller part.


center processing part.


1.       This robot can follow the line. That is why we call this robot line tracer robot.
2.       This robot consists of three parts: center processing part, sensor part, and motor controller part. 
        In this sensor part, there are 8 light sensors. 1 light sensor consists of two sensors: lighting-emitting sensor, lighting-receiving sensor. The color of lighting-emitting sensor is white and lighting-receiving sensor is black. First, lighting-emitting sensor emits the light, and then if lighting-receiving sensor receives the light, it send signal to microprocessor. In the picture, the squares that bring out the blue color are variable resistors. So, we can control the degree of the sensitivity for sensors. Finally, the sided figures that bring out the black color are LM324 chip. This chip makes the signal that is gotten from sensors to amplify in order to be suitable for the microprocessor.
           This motor controller part is made up of two circuits, but both of them are same circuit. I’ve used step motor for this robot. Step motor is very popular motor. It move 1.8 degree each signal. So, we can control exactly the speed of revolution. To control step motor, we have to use SLA7024 chip and L297. L297 divide the signal that microprocessor sends into 4 signals, and each signal is come into SLA7024. SLA7024 make step motors to move according to each signal.
            This picture is SLA7024 circuit.

            I’ve used AT89C52 chip for this robot. This is 8051 chip series.
            This is the circuit diagram of 8051 chip.

            This chip is 8-bit CPU optimized for control applications. It usually has 4k byte Rom (mine has 8k byte Rom) and 128 byte Ram (mine has 256 byte Ram). Also, we can use the maximum 24 pin for controlling some applications.
            If sensor is human’s eye or ear and motor is human’s feet, this part is like brain for this robot. In this part, 8051 chip (brain) calculates the number of rotation by using the data that sensors send. After that, 8051 chip sends signals to motor controller part.

4.       This robot needs at least 5~6 volts. Also, to turn wheels, it needs over 1A. I think that voltage should be 10~12 volts, and Current should be 1~2A.
