Mastermind With an 8x8 RGB LED Matrix

Required parts: Basys3 FPGA
8x8 RGB LED Matrix by GEEETECH
9V battery
2N3904 transistors (x32)
1K resistor (x32)
100 Ohm resistor (x1)
50 Ohm resistor (x1)
The LED Matrix is a common anode matrix with 32 total pins. The common anode means that each row is controlled by just 1 pin while each column is controlled by 3 - one for each color. The controlling for this will be done with the 32 PMOD I/O ports on each end of the board.”
