zanima me kako si ispisao ona slova na plocicu? (ono "digitalni dimer")

Digital light dimmer
Our forum user niho has just finished his light dimmer for DC current. He describes his project:
"The light level can be adjusted with two push-buttons "Up" and "Down". Controller in this application is PIC16F84 that drives BUZ11 mosfet. Dimmer is tested with a light bulb 12V/4W and mosftet didn't get even warm (which was expected since the datasheet says: 50V/30A). There is a small 5V voltage regulator on board LM78M05 (0,5 A) for the PIC microcontroller. Light level can be adjusted to 10 steps (0-9) and upon startup it is automatically adjusted to level 5. Current light level is displayed on 7-segment LED display with common anode. PCB was designed in Proteus and firmware is written in PBP."

@vfdisplay, peglom kao i sve ostalo samo sto ovdje moras stampati kao ogledalo i nije ispisano
samo dimer nego kompletan raspored i vrijednosti elemenata. A ledice sam "dimao" na
probnoj plocici prije nego sam uradio krajnji PCB kakav se vidi u projektu.
