IR LED Matrix with DMX-512 Control
A complete computer controlled lighting system implemented as an art installation was realized using the DMX-512 protocol. OpenDMX was used for sending packets along a multi-drop RS-485 bus. AtTiny2313?s were converting DMX into 8 PWM channels per vertical drop. The resulting matrix consisted of 8 rows and 15 columns with 8 IR LEDs per cell. A PC power supply was used for supplying the total of 960 LEDs with just over 19 amps of current. The PC ran DMXcontrol for visualization of music and audio.
