I / O device on the microcontroller

I am a king or not a king?

I am ready to cut the truth - quietly, quietly!

I came to you with greetings - to tell that the sun has risen

I came, I saw, I won

I can live without the necessary, but without excess - I can not

I can not be silent

I can not find a day with fire

I can not give up principles

I can promise to be sincere, but not impartial

I did not fight so much as I was fighting

I did not have time to write shorter

I did not know what I wanted: not the constitution, or the sevruzhin with horseradish

I did not like the oval from my childhood, I painted the corner from childhood

I did not notice the Elephant

I did not pass the academies. I did not finish them

I did what I could, let those who can do better

I do not agree with any word that you say, but I'm ready to die for your right to say this

I do not appreciate your gift

I do not dream about the past

I do not expect anything from life

I do not know how to think twice about the same thing

I do not know why or who needs this

I do not like to joke myself, and I will not give it to people

I do not regret, I do not call, I do not cry

I do not want to be a jester below the Lord God

I do not want to study, I want to marry

I erected a monument to myself not made by hands

I guess the crossed out number

I have a dream

I have an idea and I think it

I have very serious disagreements with the Soviet government

I hear a speech not of a boy, but of a husband

I know - the city will be, I know - the garden of flowers

I know your map

I love my homeland, but with a strange love!

I love you, I do not know, but it seems to me that I love!

I love you, what should I dissemble?

I made a tit glory, and did not light the sea

I myself am my ancestor?

I only know that I do not know anything

I promised, of course, but there is a border to everything

I recognize when I see

I saw slavish Russia

I see the beard, but I do not see the philosopher

I see through the objects

I started to live, not breathe!

I take my goods where I find it

I think, - that means I exist

I want to be cocky, I want to be brave

I want to equip a pen with a bayonet

I want to know everything

I want to live to think and suffer

I was for the Russian defendant

I was, I thought, I went through like smoke

I went to write the province!

I will not die, but I will live, because I sowed a seed verbally

I would be glad to serve, it's sickening to wait

I would have wit bureaucracy

I would like to unite my sadness and sadness

I, you, he, she, together - a whole country, together - a friendly family

If it is permissible to compare small to great

If someone here and there sometimes

If the bearing is shattered

If the child choked

If the child has lost consciousness

If the enemy does not surrender, it is destroyed

If the image on the monitor screen is unstable

If the lips of Nikanor Ivanovich yes put to the nose of Ivan Kuzmich...

If the molecules are moving, then why do not we see that things are changing?

If the mountain does not go to Mohammed, then Mohammed goes to the mountain

If they do not have bread, let them eat cakes!

If this is not true, it's well thought out

If to be, then be the first

If two people do the same thing, then it's not the same

If you want peace, prepare for war

If you want to be happy, be it

If you want to be healthy, tempered

If youth knew, if old age could

I'm avenged and I'll repay

I'm blaming!

I'm coming to you

I'm going to lead the parade

I'm going, I'm eating, I'm not fizzy, but I will not let you go...

I'm human, and nothing human is alien to me

I'm just working as a wizard

I'm not a coward, but I'm afraid!

I'm not a magician. I'm still just learning

I'm not driving here anymore!

I'm not funny when the painter is unfit for me to spoil the Raphael's Madonna

I'm not stupid reader, but more exemplary

I'm not the first, I'm not the last

I'm responsible for everything

I'm sad... because it's fun for you

I'm sad to look at our generation!

I'm strange, not strange who is?

I'm the one nobody loves

I'm tired of basking in someone else's fire

I'm writing to you - what's more? What else can I say?
