  --There are two ways to set MED Matrix: by setMatrix function like this:
  board:setMatrix(checkerboardA)
  board:wait(1)
  --Or by simple for loop and analogWrite function like this:
  for i, value in ipairs(checkerboardB) do
    board:analogWrite(gainer.SINGLE, i, value)
  end
  --Second option is slower and flickering can be seen.
  board:wait(1)
