Blinker bluetooth light

With this circuit we are able to control a 8x8 matrix led using

the max7219 chip to send the data.

  • w = up arrow
  • s = down arrow
  • a = left arrow
  • d = right arrow
  • h = heart
  • x = blinker stop

Circuit:

  • Arduino board
  • 8x8 matrix
  • max7219 led display driver
  • hc-05 or hc-06 serial bluetooth module
  • 5v power source

Connections:

pin 12 is connected to the din

pin 11 is connected to the CLK

pin 10 is connected to cs
