ATTiny to drive LEDs I'm installing some daylight running lights in my car and I have purchased 2 LED bars, each with 8 white LEDs. They use 12V and I need to make some effect when they turn on. Like in some modern cars, when I turn on the key, LEDs should blink(shake like when old fluorescent tubes turns on) and then turn on slowly(brightness from 0-100).

I can do this with Arduino-Uno and I need to put this in a smaller chip. What would be the best suitable ATTiny chip for this project? Because using an ATmega328 is not worth for a small project like this.
The ATtiny85 is an 8-pin AVR device with 3 PWM channels available in DIL and SO packages. The Arduino core can be downloaded from arduino-tiny. It can be programmed via ISP using either ArduinoISP or a dedicated programmer.
