Middle-School Coder Develops Tool to Help Teach the Periodic Table to the
  Visually Impaired

Hari Bhimaraju, a 12-year old Kennedy Middle School student from Cupertino,
California, used a Raspberry Pi and Arduino to design the hardware and
software for "The Elementor", a portable, low-cost teaching tool to help
visually impaired students learn the periodic table of elements. When a user
enters an element’s symbol with either a regular or a Braille keyboard,
pictures and animations show a model for an atom of the element, along with
light-up LEDs and sound beeps to describe the positions of the element’s
electrons. The system, which is now available for purchase, also uses a
simulated Geiger counter to provide information about radioactivity, and a
voice generation feature speaks all details out loud. In addition to winning
the 1st Place Award in Technology at the 2015 Broadcom MASTERS competition,
two schools for the blind have reviewed the tool's usefulness and are in the
process of having their students use it.
