Wearable Glove for Smart Communication

The Wearable Glove for Smart Communication is an assistive device designed to translate user input into wireless messages using radio frequency signals. At the input stage, the project utilizes four push-to-on switches (S1 through S4) mounted on a wearable glove configuration, powered by two 3.7V rechargeable batteries held in a dedicated battery case. When a switch is pressed, it provides a discrete input to the Encoder IC HT12E (IC2), which converts parallel data inputs into a serial stream format. This encoded signal is then transmitted wirelessly by the 433MHz Transmitter module (RF1). On the receiving end, the 433MHz Receiver module (RF2) captures the radio waves and passes the serial data to the Decoder IC HT12D (IC1). The decoder verifies and converts the data back into parallel signals, which are interpreted by the Arduino Uno (MOD 1). To ensure proper timing and operation, the encoder and decoder pair rely on specific passive components, including a 1-mega-ohm resistor (R1) and 47-kilo-ohm resistors (R2, R3). Once the Arduino processes the received command, it triggers local visual and audible indicators, specifically illuminating the 5mm blue LEDs (D1 to D4) and sounding the Buzzer (B1). Additionally, system feedback and status messages are rendered visually on a 16x2 LCD (MOD 2), whose display contrast is adjusted via a 10-kilo-ohm potentiometer (POT 1). Power regulation for the receiver/processing unit is managed by a 5V voltage regulator IC7805 (IC3), which steps down the voltage supplied by an external 12V, 1-ampere adapter to ensure stable electronic operation.
