Figure Lengend Snippet: Figure 1. Schematic layout and actual device. (A) The conceptual schematic organization of the touchscreen device with pieces numbered in black, corresponding to white numbers on the actual device (panels (B–D)). A Raspberry Pi controls the touchscreen and records responses. Output is then taken from the Raspberry Pi I/O pins and put through an external printed circuit board to step the voltage up to the 28 V needed for peripheral components. Physical inputs were available but not used in the current studies. (B) An image of the remote-controlled dispenser, attached to the PCB. A raspberry Pi is attached underneath the PCB and not visible. Not in this picture is the sonalert tone generator which was also hooked up to the PCB. (C) Front of testing device showing screen. (D) Rear of testing device showing back of screen, Pi, and other components. Numbered items indicate: (1) PCB, (2) RF transceiver, (3) pellet dispenser, (4) Raspberry Pi, (5) touchscreen, (6) audio speakers, (7) weighted sandbags.
Article Snippet: A Sonalert tone generator (ENV-223AM; 2900 Hz, 100 dB; Med-Associates) was also attached alongside the pellet dispenser.
