This paper presents the design and implementation of a
wearable translator device that converts hand gestures into
spoken and textual communication. Flex sensors are placed on
a glove to measure finger bending, and their analog outputs are
processed by an Arduino Nano microcontroller. Pre-recorded
voice messages stored on an SD card are played through a
DFPlayer Mini module and a compact DC speaker, while
an LCD screen displays text corresponding to the detected
gesture. The device further supports PLC interfacing for external control. Experimental evaluation demonstrates reliable
gesture recognition and real-time output performance suitable
for assistive applications. The system offers an affordable and
portable translation aid for users who rely on sign language.
Keywords: sign language, flex sensors, DFPlayer Mini, Arduino Nano, gesture recognition, PLC interfacing.
