A11Y IRL (Accessibility in real life)
summary
An open source IoT Braille reader is prototyped using Arduino and Johnny-Five, driving six solenoids per Braille cell and controlled with roughly 30 lines of code. The prototype runs from parts bought on eBay/Amazon, demos reliably, and soldered builds hit ~2–3 ms latency. Context stats: about 253 million visually impaired people and only 8.5% Braille literacy in the U.S. motivate further miniaturization and a move to stepper motors.
