Course Content

Basics of Electronics:

• Understanding voltage, current, and resistance (Ohm’s Law)
• Introduction to circuit components: Resistors, Capacitors, Diodes, LEDs, etc.
• Understanding circuits: Series vs. Parallel

Using breadboards, multimeters, and power supplies.

Setting up basic circuits on a breadboard:

• Connecting components like LEDs, resistors, and switches.
• How to use breadboards effectively for quick prototyping.
• Building simple circuits and troubleshooting them.

Working with resistors:

• Different types of resistors and their uses.
• How resistors control current in a circuit (practical applications with LEDs).
• Calculating and selecting the right resistor for different applications.

Understanding LEDs:

• How LEDs work and their applications in circuits.
• Connecting LEDs to breadboards and controlling them with resistors.
• Using multiple LEDs in circuits (e.g., blink patterns and color mixing).

Using push buttons and switches in circuits:

• Understanding the role of switches in controlling the flow of electricity.
• Building circuits where buttons control LEDs or other components.

Introduction to Microcontrollers (e.g., Arduino, Raspberry Pi, ESP32):

• Setting up a simple microcontroller board.
• Writing basic programs to control LEDs, sensors, and motors.
• Understanding digital and analog signals in programming.

Connecting OLED Displays:

• Setting up an OLED display with a microcontroller.
• Programming the display to show text and graphics (e.g., “Hello, World!”).
• Practical applications like temperature or humidity display.

Fingerprint Scanning Basics:

• Understanding how fingerprint scanners work and their role in biometric systems.
• Using a fingerprint sensor module (e.g., R305 or GT-521F52) to capture fingerprint data.
• Programming the sensor for enrolling fingerprints and verifying identities.

• Objective: Create a fingerprint-based biometric attendance system.
• Tasks:
  1. Integrate a fingerprint scanner with a microcontroller (Arduino or Raspberry Pi).
  2. Program the scanner to enroll fingerprints for different users.
  3. Set up an LCD or OLED display to show attendance status (e.g., “Welcome [Name]” or “Attendance Recorded”).
  4. Develop a simple database (using an SD card or cloud storage) to track attendance logs.
  5. Implement real-time fingerprint recognition for attendance verification.

Using Sensors:

• Temperature, motion, and light sensors to create interactive circuits.
• How sensors interface with microcontrollers for data collection.
• Examples: Temperature monitoring systems, motion detectors for security.

• Objective: Develop a complete biometric attendance system.
• Tasks:
  • Design and build the system using fingerprint sensors, microcontrollers, and display modules.
  • Implement software to manage user enrollments, attendance logging, and verification.
  • Present the final project, showcasing the working system with real-time data and attendance tracking.
