Bluetooth Bingo Display for the Hearing Impaired #AssistiveTech #Hearing #Gaming @Instructables
By dick55 on Instructables, who has designed and built a box to display bingo card selections via Bluetooth.
My wife and I meet friends and family once a week to play Bingo at a local restaurant/bar. We sit at a long table. Facing me is a man with impaired hearing and vision. The room is very noisy and the man often has to ask his wife to repeat many of the numbers called out. So I decided to make the two-unit Bluetooth-coupled system pictured above. On my unit I enter the number called and he sees it on his unit.
The transmitting unit has a 12-key telephone type keypad. Five of the keys (1, 4, 7, *, 0) are programmed to enter the BINGO alphabetic character of each new number called. This unit also has a 4-character display, with 14-segment LED alphanumeric characters showing the complete number (e.g., B-15).
The receiving unit has the same display, whose size and brightness is more than adequate for the intended viewer. While the transmitting unit sits flat on the table, the receiving unit can also be tipped up for better viewing.
See Instructables for the full parts list and build instructions along with the Arduino code.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
