60 Years of Misery...and Then You Die!!!

Now I have my exciting new STP16C596 LED driver (datasheet), it’s time to update my previous project. It’s pretty simple to get it working, and when you do you’ll have cut the amount of pins used on the Arduino down to 3. For the eager amongst you, here’s the PDE; it lights up the LEDs [...]

One of my first Arduino projects; a 3×3 LED matrix. Pretty simple design, but based on a few interesting facts… A 3×3 matrix equals 9 LEDs, equals 9 input (+ve voltage) 1 output (ground) pins, equals a mess of wires and breadboard trickery…or so you’d think. Using persistence of vision, we can get by with [...]
