Step 5 You may now try adding different circuit components, writing, and simulating the code
before using a real Arduino!
Hands-on Task:
Try setting up Tinkercad Circuits and build a simple project using this QR Code.
REVISIT
▶ Voltage, Current, Resistance are the bedrock of circuit understanding.
▶ Resistors, Capacitors, and LEDs have unique roles—limiting current, storing energy, and emitting light, respectively.
▶ A breadboard lets you build and test circuits without soldering, using rows/columns of interconnected holes.
▶ Microcontrollers (like Arduino) allow you to create interactive and programmable electronic systems.
▶ Arduino IDE is your primary tool for coding the microcontroller.
▶ Tinkercad Circuits provides a virtual sandbox for testing circuits and code.
Hands-On Challenges
Virtual vs. Real: Build the same LED blink circuit in Tinkercad and on a physical Arduino
board. Compare your experiences.
By completing these activities, you’ll develop a hands-on familiarity with crucial electronics
principles and the confidence to move on to more advanced robotics and IoT projects.
In lesson 2, you will explore how to control outputs and manage timing—the core ideas that
power signal lights and indicator systems. This will lead into your first larger project: a Traffic
Light Simulation using multiple LEDs, timed sequences, and the code you’ve just begun to
master.
Remember: Electronics and microcontrollers are all about experimentation. Don’t hesitate
to make small modifications, observe results, and learn through trial and error. Enjoy the
journey!
