Don't know if I've come to the right place to ask questions but According to the picture provided, what am i doing wrong???! There's no power to the 7 segment display or it just won't light up. Are my writings wrong.? Could it be my resistor values? It didn't seem like I was getting any power to my output pins of the 7447 led decoder. Please help asap. need it to work for a lab grade. Class ends in 1 wk. it would be much appreciated!
