Part 2: Recreating and Building Real Circuits

  • Objective:

To provide students with hands-on experience in recreating and building real circuits based on their virtual designs.

  • Resources:
  1. Electronic components (resistors, LEDs, batteries, switches)
  2. Breadboards
  3. Jumper wires
  4. Multimeter
  5. Safety goggles
  • Time: 60 min
  • Component Selection and Preparation (10 min):
  1. Provide students with the necessary electronic components for recreating their virtual circuit designs.
  2. Explain how to identify the real components that correspond to the ones used in the Tinkercad designs.
  3. Demonstrate how to prepare the components by bending the leads and ensuring proper polarity for LEDs and batteries.
  • Building Real Circuits (25 min):
  1. Instruct students to recreate their virtual circuit designs as real circuits on the breadboard.
  2. Guide them in placing the components on the breadboard, connecting them using jumper wires, and ensuring proper connections.
  3. Encourage them to follow the original design and pay attention to the component placements and orientations.
  • Testing and Troubleshooting (20 min):
  1. Assist students in testing their real circuits using a multimeter to measure voltage, current, and resistance.
  2. Encourage them to compare the behavior of the real circuit with the simulated version in Tinkercad Electronics.
  3. Help students troubleshoot any issues they encounter, such as loose connections or incorrect component placements.
  • Conclusion (5 mins):
  1. Summarize the key points covered in the session, including the translation of Tinkercad designs into real circuits.
  2. Emphasize the importance of accuracy, attention to detail, and safety when building real circuits.
  • Assessment:

Observe students as they work on the virtual circuit design, noting their understanding of component selection, circuit building, and their ability to troubleshoot and test the real circuits.

  • Homework:

Assign students to design a new circuit in Tinkercad Electronics and create a corresponding real circuit based on their design for the next session.

Example homework:

  1. Design and build a simple flashlight circuit using Tinkercad Electronics. Include a switch to turn the flashlight on and off.
  2. Create a circuit that makes an LED blink at a specific frequency. Experiment with different resistor values to adjust the blink rate.
  3. Design a circuit that plays a melody using a piezo buzzer. Explore different tones and create a simple musical composition.
  4. Build a circuit with multiple LEDs of different colors. Use a switch to control the LEDs, creating a traffic light simulation.
  5. Create a circuit that detects and reacts to light. Use a light-dependent resistor (LDR) to control the behavior of an LED.
  6. Design a circuit that uses a push-button switch to activate an alarm or a sound effect.
  7. Build a circuit with an RGB LED and experiment with different combinations of colors by adjusting the voltage levels.
  8. Create a circuit that measures temperature using a temperature sensor (such as a thermistor) and displays the temperature on an LCD screen.
