Holiday Project: Dot-Matrix LED Ornament


Are you looking for a unique decoration for a special Christmas present? Then consider building this inexpensive ornament for adorning your next gift. You can easily hard-wire the 5x7 dot-matrix LED into just about any visual configuration that will fit within a grid of 35 green/red pixels. We have presented you with two templates for wiring a Christmas tree configuration. Refer to the BG Micro datasheet for the relevant wiring connections. For the more versatile gift box accoutrement, however, this simple programmable dot-matrix LED uses DIP switches for illuminating rows/columns of pixels. Granted, this project isnt as flexible as individually programmable pixels, but it should help you get started with building your own more complex dot-matrix LED Ornament.
