This idea came when I left the pedal working in my studio during the night. It makes a cool red light and I thought that it would be cool to make a bedside table lamp with it:

• This code light more bars as you move the encoder up and down.
• If you want to change the intensity because it's too bright, you can also modify it on the init of the 8x8 matrices:

  lc.setIntensity(0, 14);
