Giant Scrolling LED Sign Powered by One Arduino Costs Around $15/Foot
Building off the previous work
parallel bit-banging eight NeoPixel strips from one controller, this time around josh.com shows how to build a giant scrolling LED sign, for about $15/foot using similar materials. That’s pretty cost effective for the results:
Would you do with a massive full color animated LED display? How about…
Read your Tweets in giant 140 char gulps from a block away
Add English sub-titles to the Eiffel Tower
Display a live-updating, 45 digit long countdown of the number of atoms left in the known universe
What if you could build the display however long you needed it, for only about $15/foot?
What if it was really easy to build and used everyone’s favorite low cost micro-controller so you could easily change the software to do whatever you wanted?

Make a robot friend with Adafruit’s
CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
