Display 7 Segmentos 12v con arduino uno

Este es un buen punto de partida

12V 7 segment LED display

Your circuit is not correct. Try it like this. TPIC6B595 can not drive high, need a pullup resistor to turn off the P-channel MOSFET that sources current into the anodes of the segment. N-channel MOSFET is not the right part. [12V Common Cathode segment driver with MOSFET.jpg]
