Lecture 1: Introduction to the Circuits Simulator:

• Description: Learn the Tinkercad Circuits interface, the component library, and the basic principles of electricity (voltage, current, resistance). You will build your very first circuit to power a light.
• Key Concepts: The Tinkercad Circuits workspace, components (battery, resistor, LED), wiring, and starting a simulation.
• Hands-on Project: Build a simple circuit with a 9V battery, a resistor, and an LED.

Lecture 2: Your First Microcontroller: The Virtual Arduino:

• Description: We'll introduce the virtual Arduino UNO board and the breadboard as a prototyping tool. You'll learn the structure of an Arduino program and write the code for the classic "Blink" sketch.
• Key Concepts: The Arduino UNO board layout, the breadboard, pinMode(), digitalWrite(), and the delay() function.
• Hands-on Project: Build an Arduino-controlled LED circuit and program it to blink.

Lecture 3: Digital Inputs and Conditional Logic:

• Description: Learn how to use inputs to control your circuits. We'll connect a push button and use if statements to make your code respond to a button press.
• Key Concepts: Digital inputs, digitalRead(), internal pull-up resistors, and basic conditional if-else statements.
• Hands-on Project: Build a circuit where pressing a button turns on an LED.

Lecture 4: Analog Signals and PWM:

• Description: Move beyond simple ON/OFF signals. You'll learn about analog inputs using a potentiometer and how to control an LED's brightness with Pulse Width Modulation (PWM).
• Key Concepts: Analog vs. digital, analogRead(), analogWrite() (PWM), and the map() function.
• Hands-on Project: Create a dimmer switch: use a potentiometer to control the brightness of an LED.

Lecture 5: Sensors and Advanced Components:

• Description: Give your circuit the ability to "see" and "act." We will integrate a sensor to measure distance and use a servo motor for precise movement, all virtually.
• Key Concepts: Ultrasonic distance sensor (HC-SR04), reading sensor data, and controlling a servo motor using the Servo library.
• Hands-on Project: Build a simple "proximity alert" system that turns on an LED when an object is too close to the ultrasonic sensor.

Lecture 6: The Final Project Showcase:

• Description: This final class brings everything together. You will integrate a push button, multiple LEDs, and conditional logic to build a complete, simulated project.
• Key Concepts: Project planning, circuit design, and code integration.
• Hands-on Project: Build a smart traffic light with a pedestrian crossing button.
