Smart Gloves for bed ridden people using Arduino UNO

 

 Smart Gloves for Bedridden People Using Arduino UNO

Project Overview

Smart Gloves for Bedridden People is an assistive technology project designed to help patients who are unable to speak or move freely communicate their needs easily and independently.

The system uses the Arduino Uno, flex sensors embedded in a glove, and an I2C LCD display to convert simple finger movements into meaningful messages.

When a user bends a finger, the flex sensor detects the resistance change. The Arduino processes the signal and displays a predefined message on the LCD screen for caregivers to read.

Components Used

• 1 × Arduino Uno

• 3–5 × Flex Sensors

• 1 × 16x2 I2C LCD Display

• Resistors (typically 10kΩ for voltage divider)

• Breadboard

• Jumper wires

• Glove (fabric base)

---

Working Principle

 1. Flex Sensor Operation

• Flex sensors change resistance when bent.

• More bending → Higher resistance.

• Connected in a voltage divider circuit.

• Arduino reads analog values from sensors.

---

 2. Gesture Detection

• Each finger corresponds to a specific message.

• Arduino compares sensor readings with predefined threshold values.

• If bending exceeds threshold → gesture detected.

---

 3. Message Display

• Once a gesture is recognized:

  • Arduino displays a predefined message on the I2C LCD.

• Caregiver reads the message instantly.

💬 Example Gesture Mapping

Finger Bent	Message Displayed
Thumb	“I need water”
Index	“I am hungry”
Middle	“I am sleepy”
Ring	“I need washroom”
Multiple Fingers	Emergency Alert

 Basic Circuit Concept

 Flex Sensor (Voltage Divider Setup)

• One end → 5V

• Other end → 10kΩ resistor → GND

• Junction point → Arduino Analog Pin (A0, A1, A2...)

---

 I2C LCD Connections

LCD Pin	Connect To
VCC	5V
GND	GND
SDA	A4
SCL	A5

(I2C reduces wiring complexity.)

---

Basic Arduino Logic (Concept)

int flex1 = analogRead(A0);

if (flex1 > 600) {
  lcd.setCursor(0,0);
  lcd.print("I need water");
}

(Repeat logic for other fingers.)
