This example models a middle school electronics project using real-world circuit principles like Ohm's Law, ensuring clarity and reproducibility for STEM education.
Title
How Does Resistor Value Affect LED Brightness in a Simple Circuit?
Abstract
This project investigates how changing resistor values impacts LED brightness in a basic circuit. Using Ohm's Law ($$V = IR$$), three resistor values (100Ω, 220Ω, and 470Ω) were tested with a constant 5V power supply. Results showed that lower resistance allowed higher current flow, producing brighter light output. This experiment demonstrates practical applications of basic circuit design in electronics and robotics systems.
Introduction
LEDs (Light Emitting Diodes) are widely used in robotics projects and embedded systems. Controlling brightness is essential for indicators, displays, and sensors. According to the U.S. Department of Energy, LEDs consume up to 75% less energy than incandescent lighting, making them efficient but sensitive to current changes. This study explores how resistor values regulate current and brightness.
Research Question
How does changing the resistor value affect LED brightness in a 5V circuit?
Hypothesis
If the resistor value increases, then LED brightness will decrease because higher resistance limits current flow according to Ohm's Law.
Materials
- Breadboard and jumper wires.
- Arduino Uno (5V output).
- LED (red, 2V forward voltage).
- Resistors: 100Ω, 220Ω, 470Ω.
- Multimeter for measuring current.
- Power supply (USB or battery).
Methodology
- Set up a simple LED circuit using a breadboard and Arduino 5V output.
- Insert a 100Ω resistor in series with the LED.
- Measure current using a multimeter and observe brightness.
- Repeat steps using 220Ω and 470Ω resistors.
- Record all observations and measurements systematically.
Results
The experiment produced measurable differences in brightness and current, confirming theoretical predictions from Ohm's Law principles.
| Resistor Value (Ω) | Measured Current (mA) | Observed Brightness |
|---|---|---|
| 100Ω | 28 mA | Very Bright |
| 220Ω | 14 mA | Moderate |
| 470Ω | 6 mA | Dim |
Discussion
The results align with the equation $$I = \frac{V}{R}$$, showing that current decreases as resistance increases. Lower resistance allowed more current, making the LED brighter. This principle is widely used in microcontroller-based systems such as Arduino and ESP32 to protect components and control output levels.
"Understanding current control is fundamental to safe circuit design," notes Dr. Lina Perez, IEEE STEM Education Report, 2022.
Conclusion
This experiment confirms that resistor values directly control LED brightness by limiting current. These findings are essential for designing efficient circuits in beginner robotics education and embedded electronics projects.
