Arduino Bluetooth POV Display

Sunday, August 23, 2015








Let's make it -

Visit here to see it updated version - (without Bluetooth controlling option)

"ARDUINO POV DISPLAY: THE BEST TUTORIAL TO START!"


Circuit diagram


This is a simple bluetooth pov (persistence of vision) display made using arduino and Hc-06 bluetooth module and 8 led

code for five led display without bluetooth module
