Should you solely care about exhibiting content material as clearly as doable on the lowest price, you then’ll wish to flip to LCD or OLED know-how. However a venture’s show provides you a chance to get inventive with the aesthetic, which opens up a complete world of various show varieties. In order for you a retro really feel, then you’ll be able to inspiration in DIY GUY Chris’ beautiful LED matrix.

This can be a dot-matrix LED show with an total decision of 32×8. However that description alone doesn’t do the venture justice. Chris used tiny 0603 SMD LEDs, which allowed for very excessive “pixel” density and that leads to higher readability than a typical LED matrix show. To allow future growth, Chris set this up as a number board that accepts 4 LED boards — every of which comprises an 8×8 matrix. A MAX7219 IC drives the LEDs on every of these boards.

The LED boards hook up with the host board via nifty mezzanine connectors. The host board comprises an Arduino Nano that sends management alerts to the MAX7219 chips. The Arduino can provide USB energy to the LEDs, however there’s additionally a DC jack for energy when USB isn’t linked. Chris’ Arduino sketch lets the person “print” alphanumeric characters to scroll throughout the 4 LED matrices.

The most effective half about this design (apart from the good type) is that Chris can scale it up sooner or later with bigger host boards that settle for greater than 4 LED boards.
