Project Aim:

To understand the fundamental concept of sensors and their application in converting physical inputs into electrical signals.

Components Used:

1. Power Supply

2. Touch Sensor

3. Resistor 220Ω

4. LED

5. Connecting Wires

Circuit Diagram:

Connection Procedure:

Step 1: Connect the Positive terminal of the Power Supply (Pin 62) to the Touch Sensor (Pin 77).

Step 2: Connect the Output pin of the Touch Sensor (Pin 78) to one end of the Resistor 220Ω (R2, Pin 3).

Step 3: Connect the other end of the Resistor 220Ω (R2, Pin 4) to the Anode of LED (Pin 47).

Step 4: Connect the Canode of LED (Pin 48) to the Negative terminal of the Power Supply (Pin 59).
Step 5: Whenever we put finger on Touch Sensor, the LED will glow.

Explanation:

This project introduces the concept of sensors, which are devices that can detect various inputs like light, heat, motion, and convert them into electrical signals. In our circuit, we utilize a touch sensor that detects the touch of a hand, converting it into electrical pulses. When a touch is detected, the circuit completes, allowing current flow and triggering the output, which will glow the LED. Through this project, we gain hands-on experience in understanding sensor functionality and circuit completion for practical applications.
