I finished my project with Arduino, and now i want to free arduino board to use it in another project. I've found this: http://arduino.cc/en/Main/Standalone#.UxRQtEW4C00 But i want to use serial connection, not USB. After googling a bit, i've found this: http://www.hobbytronics.co.uk/arduino-atmega328-hardcore Is this right thing? Only a few resistors and two transistors is all i need? I have BC547B transistors instead of BC548 is it ok? Or it have to be exactly BC548?
Sorry if i hit wrong section for this topic.
