i need to count a pairs in poker, but i didn’t realise how do it

I'm working at automatic texas poker, and now i constructing a component, that getting an input with 5 signals, that is a cards on the board, and 12 signals, that is a cards in player's hands (2 for each player). So this component need to calculate, what combitation each player have (pair, two pair, triple, full house or quadro). All cards are open, and looks like restone signal between 1 and 13 (from 2 to ace). Space is unlimitted, but inputs are placed like on photos. Thank you for help! When i will done my poker, i will post it on reddit
