DIY: LED Dot-Matrix Display
Make your own cool LED Dot-Matrix display and make sure its the life and light of the next party you throw.
“First thing to do is to add all the support stuff for PIC, so I need power supply, download socket and reset. I also need to arrange the outputs in simple to use rows. This defined the size of the PCBs so I spent as much time as I could reducing the size until I couldn’t get it any smaller.”
“The next step was to place the 20 LEDs in the dot-matrix, connectign all the anodes in columns and all the cathodes in rows. This is impossible to do without using link wires unless your using double layer board or double sided board. I wasn’t so I will be using link wires.”
