when i started building arduino brain machines i had a bunch of minipov boards left lying around, so i built one with uv leds. works pretty well. has it’s own font built in and room for about 950 characters of message. as presented here, there is an output bug at the end of the second line, but i reckon i’ll work on that in the morning. meanwhile, i can wave it around and wipe poetry onto a piece of butcher paper painted with fluorescent paint. here’s some not very good video of the chemical pov running the above code. the light does persist a little longer than it appears to in the video, but i think it will work better when i replace the current limiting resistors.
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.
