Hey guys i´ve ben trying all day to upload sketches to my ATTiny84A. I tried it with this Tutorial but im guessing it´s diffrent with a Mega 2560 right? I couldn´t find any clear instructions on this.
Error Code :avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
Please help me
You've given no information about what tutorial you're using or what problem you're having. We can't help if you don't tell us anything.
Sry forgot to inject the link xD Tutorial
You have not described your problem - but that tutorial is ancient, and the requirements of boards.txt have changed since then; it will not work on recent versions of the IDE.
Why are you going to all that work instead of using a third party board package that someone else has prepared, like my ATTinyCore? It should work right out of the box without you having to go modifying files.
Thanks man thats a huge step forward. I did the Wiring as advertised in the Thread but it´s only described for VCC and GND or did is miss something ? Maybe it´s this graphic but i can´t understand it Graphic
Thanks for ur Help 
I did like displayed in the Graphic but it gives me this error
The Error Code now changed to

Hey Guys i tried everything i could find maybe my ATTIny is broken ? Can u please help me?

avrdude done. Thank you.
Dieser Bericht wäre detaillierter, wenn die Option
"Ausführliche Ausgabe während der Kompilierung"
in Datei -> Voreinstellungen aktiviert wäre.
Sig reading all 0's is 99% of the time either wiring problem, or you've set the chip to use an external crystal or clock source, but one isn't connected.

I'm experiencing exactly the same error with my ATTiny. I solved it yesterday, I explained how here: ATTINY 84 in Arduino IDE on a UDOO: Nothing shows up in "Programmer" section - Microcontrollers - Arduino Forum
but I have it again today, woth exactly the same wiring and exactly the same method of programming it. Apparently it's just luck if it works.

Maaan ur a god! It worked just perfectly ur description was as easy as walking forward is.. Love it.
Hope you have luck with ur one 2 
Is it normal that the Attiny gets hot he´s about 100 degrees :(...

Mine did that too, you're probably putting too much current through it. Try using a resistor.
Should i put the Resistor in series with + ? ANd which kind of resitor ? Im powering it with a 5v powerbank i measured it and it´s 5v....

The current shouldn't exceed 40mA. I hope someone is an expert on resistors but as
R = U / I
you should measure your current and put a light resistor between + and VCC so that your current is under 40mA. The ATTiny works with very small currents though so just put any resistor in and try with that.

No, absolutely not. you've connected something very wrong if it is...
Which of course would explain the difficulty in programming it. You may have damaged the chip at this point.
No he hasn't, I've had this happen as well. He said that programming works now.
I think i shortet it 
thats why it heatet up so heavy. But i can still programm it with no errors. Now i found out the pwm and do outputs and find them but i have no idea to find out which pins are analog in, cuz i need them for a bigger sketch. U can find it below. could someone tell me is it possible to get it working with my attiny84A ?

Yeahi was thinking of that 2, but what do i type ?
pinMode(PA1); ?
LichtValue = analogRead(PA1); ?
pinMode(1,INPUT); //this pin is different if using the counterclockwise pinout
LichtValue=analogRead(A1);
See the pinout chart included with the core. Use digital pin number for pinMode(), not analog pin number, as per the warning in the documentation; this limitation will be fixed in a future release.
Note also that pins are set input on powerup, and don't need to be set to INPUT unless they were previously set to something else.
