These were part of a giant message board that flashed “SLOW DOWN” when a driver would approach at a high rate of speed. They were sold to us because disgruntled drivers shot bullets into them – destroying some circuit traces. These use a large quantity of super bright daylight visible red LEDs and are about 15” Height x 21” Width (Total from 2 boards). The LEDs spell out “Slow Down”. We have no data but the set of 2 boards is being sold as is since atleast one or both of the boards have bullet holes in them.
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.
