12+ Scr Pin Diagram. Control and status signals 5. All unused pins on the microcontroller as routed out to 0.1 headers along the edges of the board and are conveniently labeled with their port and pin.
Power supply and clock signals 2. The address bus has 8 signal lines a8. Optocoupler 1 collector pin is connected to arduino pin 2 which is external interrupt pin, so optocoupler 1 interrupts.
The diagram shows the load voltage waveforms that can be generated.
