editCourse Objectives
- Primary Objectives- By the end of this challenge, students will be able to:
- Read a schematic and make basic electronic circuits using resistors and LEDs.
- Understand and use breadboards, power supplies, and digital multimeters (DMMs).
- Understand and use units in basic electronics
- Sub Objectives- The objectives will require that students be able to:
- Use breadboards and power supplies.
- Measure resistance, voltage, and current using a DMM.
- Connect and measure resistors in parallel and series.
- Apply Ohm’s Law.
- Understand and use LEDs.
- Understand and apply Kirchhoff voltage law.
- Compute power and energy consumption by resistors and LEDs.
- Difficulties- Students may have difficulty:
- Correctly using the correct relationships and units between voltage, current, and resistance.
- Correctly using breadboards, color code wiring, and power supplies to implement basic electronic circuits.
- Correctly using DMMs to measure current, voltage, and other parameters because not only they need to know the correct lead connections but also setting the knob of the DMM to the right place and range.
- Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
- There are many applications that use basic electronic circuits including resistors and LEDs: traffic lights, flash lights, street lights, monitoring systems, video game systems, etc.
LEDs - Learning the mentioned concepts and acquiring hands-on experience in basic electronics are intended to be the first steps to encourage students to pursue a career in a STEM field, such as electronics, semiconductors, measurements and instrumentation, mechatronics, and control systems.
- There are many applications that use basic electronic circuits including resistors and LEDs: traffic lights, flash lights, street lights, monitoring systems, video game systems, etc.
