Looking to understand exactly what resistors do?  In this bonus project, you’ll use various resistance levels and see the impact they have on LED brightness and voltage levels. 

What You’ll Learn

When you are finished with this project, you’ll be able to:

  • Build a circuit using LEDs and resistors
  • Compute voltage across a circuit with resistors. 
  • Understand what a higher resistance level does to LED brightness. 

What You’ll Need

To complete this project, you’ll need the following components

Build your resistance circuit

Code your resistor circuit

Watch resistance in action!

Once your circuit is built and coded, watch the serial monitor in the Arduino web editor or IDE to see the variations in voltage levels, and look to see which LED is brighter!
