This week we take a look at using a shift register to control a single 7 Segment Display then we take a look at the Maxim 7219 chip that is designed specifically for controlling up to 8 7 Segment displays or an 8x8 LED matrix. Plus you can connect these chips serially like a shift register to add control of an additional 8 displays for each additional chip.
