FaceBlock

An 8x8 LED Matrix - it is a like a super LetterBlock.

You can join more than one FaceBlock together to make a pair of eyes that you can animate for the Face of your robot.

• Theory

  
  
  
  
  The FaceBloX is an 8x8 LED Matrix. Since it would take 64 outputs to control all the LEDs it has its own microprocessor (brain). We only need 5 wires to connect to it. Two for power, and three for communicating.
  
  You can chain multiple FaceBloX together for an even bigger display.

• You can use 2 FaceBloX to create a face for your DashBot (similar to the picture below)

• mBlock

  
  
  The FaceBloX needs the RoboBloX Extension installed

• Here is a program the helps you understand how to turn your binary (base 2) image
  into decimal (base 10) numbers:

• How to use the FaceBloX in Arduino Mode

  faceblox.picture(0,0,0,0,0,0,0,0,  129,66,36,24,24,26,66,129);    //16 columns of bytes (8 for each matrix)     
  faceblox.scrollText("Your Message Here", 25, 1);        	   //25 is the speed (percentage), 1 is the spacing

  The first 8 numbers are for a second FaceBloX
  the next 8 numbers are for the first FaceBlox.
