How to use ATTINY4313 Microcontroller

ATTINY4313 works like any other microcontroller. If stated in one sentence, all that microcontrollers do is execute the application program saved in its memory. So, in the case of controllers, all there is to do is write an application program. Without programming controller simply stays idle. ATTiny4313 can be connected and programmed using Arduino. For that, you need to download the board information for ATtiny4313.
