I need help displaying the correct values $$on my $4$d$7$s screen. My sonar reads the distance correctly, but when I try to display the value on the screen, none seem to work. Only seven b$0111000,//7$:ABC $-->$ the only digit displayed correctly works because I played around with the binary value until I got seven.
