3D Color LED Graphics Display using ATmega32 microcontroller

This 3-dimensional graphics display system which named as MaJaTron consists of 125 RGB LEDs arranged in a cube of 5x5x5 dimension. Each LED is a multicolor Red, Green and Blue LED and the control circuit of the system can individually control the intensity of each color, thereby, creating a full color, graphics system. Each LED is independently controllable. To control these 125 …
