Step 12Testing the LED Matrix
This is probably late in the game to consider testing, but better late than too late. Before installing the LED matrix in the umbrella (next step), hook up the matrix to the Arduino and run the test code included below. The code just runs through each LED and tests it. If any connections are bad or LEDs are broken, fix them now while everything is accessible.
This is also the time to determine which pin corresponds to which row or column. If you were careful when making the pin headers, you already know. Otherwise, you will need to figure it out by slowing down the animation and determining which pin controls which row or column. You set an array in code which contains the pin numbers in the correct order.
