ATtiny85 minimum setup to blink led
This schematic shows a complete connection of a blinking led.


Red cable = +5V (pin 8)
White cable = Ground (pin 4)
Resistor = 1 end at pin 5 (IO 0) and the other in the LED anode (+)
Led anode (+) in the resistor, cathode (-) (small leg) in the ground
Resistor = 330 Ohms


The arduino in the picture is not necessary, just used to give power. But in the video linked below its used to burn the ATtiny85. The resistor can be a 330 ohms for a simple project like this.



Youtube Video with a simple explanation

I hope this explanation will enlighten who wants to start on it.

Edited:

If you want to record your ATtiny85 using Arduino UNO as ISP, then you will also need:


10 uF electrolytic capacitor


Here a picture of the pins:
