Side-Scrolling LED Display
For this article, I will discuss an electronics project that uses an old Gameboy Color as a microcontroller to drive and control the side-scrolling LED stock ticker shown in Figures 1 and 2. The LED stock ticker consists of 105 x 7 dot matrix LEDs that are cascaded into a 50 x 7 LED screen. The whole project is wire-wrapped and running at a frequency much less than eight MHz.
