Summary of 3D Color LED Graphics Display using ATmega32 microcontroller
MaJaTron is a 3D graphics display system featuring a 5x5x5 cube of 125 individually controllable RGB LEDs. The system utilizes 13 ATMega32 microcontrollers, where each chip manages 10 LEDs via a pseudo-RS232 network receiving data from a PC. Operating at 230400 bps, the setup achieves over 30 frames per second for full-color animation, inspired by Cubatron.
Parts used in the MaJaTron:
- 125 RGB LEDs
- 13 AVR Microcontrollers ATMega32
- Pseudo-RS232 network
- PC for data input
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 LEDs, a control circuit consisting of 13 AVR Microcontrollers ATMega32 is used.
Each ATMega32 controls 10 LEDs. All the microcontrollers are networked together in a pseudo-RS232 network. This network gets the pixel color and intensity information from a PC. The Mega32s are programmed to operate at a rate of 230400 bps, thereby providing a frame update rate of more than 30 frames per second. This 3D Led Animation project is inspired from Cubatron.
