LED matrix







  • I just got some MAX7219CNG . the MAX7219CNG is ment to drive 7 segment display or 8 x 8 matrix. I guess its time for me to play with more things. For awhile I have been stuck on making a matrix or controlling a matrix . For me this makes things more interesting for me. I still havent played with shift registers yet.



  • Oh this is really cool idea for a simple display.



  • I like how this guy breaks things down.



  • these are fun to play with.



  • I used this method.



  • Today I just got in the mail some cd4026be. Seven segement display drivers. I ran the clock off of a 555 ic. I have been stuck on this for a long time due to not having the proper part.

  • You could check with us for this kind of thing. Scorpion has a LOT of TTL and CMOS chips.

  • As you can see that I am interested in such things.



  • This is cool. Shows how max7219 works.



  • This is cool fofor a DIY project



  • Thought this was interesting.



  • I got my hands on an older prolite. I opened it up to see how it works. It uses ulb2003. I now know why. I first seen uln2003 as a 5V stepper motor driver.
