Tv-b-gone mit Attiny13 (Elektronik)

/*
The hardware for this project is very simple:
ATtiny2313 has 20 pins:
pin 1 connects to serial port programming circuitry
pin 4 one pin of ceramic resonator
pin 5 one pin of ceramic resonator
pin 10 ground
pin 12 PB0 - visible LED
pin 14 OC0A - IR emitter, through a 2N3904 driver (with 120 ohm base resistor)
pin 17 connects to serial port programming circuitry
pin 18 connects to serial port programming circuitry
pin 19 connects to serial port programming circuitry
pin 20 +3v
All other pins are unused
This firmware requires that the clock frequency of the ATtiny
is the default that it is shipped with: 8.0MHz
IMPORTANT: to use the ceramic resonator, you must perform the following:
make burn-fuse_cr

Wie so ein µC grundsätzlich beschalten gehört, findet man schnell im Internet, zB auf Mikrocontroller.net. Das sollte eigentlich riechen oder etwa nicht?
