8 Hardware Design

This specific subsystem example requires nine LEDs, three resistors, and at least six wires. To setup the matrix, arrange the LEDs in 3 × 3 rows. Connect the cathodes of each row of LEDs together. Then, connect the anodes of each column of LEDs together. Connect a 220Ω resistor to each column line. From there, connect the row lines and column lines to the correct device pins based on the device configuration. See Figure 1-1 for connection guidelines.
