So I got an 8051 trainer board. I got it because in class today while connecting from port 2 into the bar led LEDs were cutting g in and out. We'd put another wire In LEDs would cut off. Also some of the ports weren't lighting the LEDs they were supposed to. I was thinking there might be some sort of bad connection at the output pin and board. Or something might have gotten burnt up somehow else. Everything visually looks good
