I was trying to make a circuit using 7 segment and arduino logic state and I am successful in showing binary number on 7 segemnt as take input from logic state but now when I am trying to code for gray code like I wanna show 2 binary into Gray that is 3 not working any idea As I use arduino pin 12,11,10 for input for binary representation but pin 4,5,7 for gray representation but I'm stuck in gray I'm using xor gate but it's not working

grey2bin(unsigned n){
  unsigned m=n;
  while(n>>=1) m^=n;
  return m;
  • \$\begingroup\$ No actually on arduino I'm using pin 12 11 10 3 pin of arduino for input and it is connected with ic and then 7 segemnt this one showing binary and pin 4 5 7 for gray code it is connected with ic and 7 segment but when I code for gray at pin 4,5,7 I wrote pin mode input and a ^b^c but it's not working hope u get my point \$\endgroup\$ Commented Jan 5, 2021 at 11:37
  • \$\begingroup\$ you should combine those pins to make a binary number, convert from gray and then do whatever you need with the binary. \$\endgroup\$ Commented Jan 5, 2021 at 13:13
