Dive into the world of electronics and programming with our Resistor and LED Activity using Arduino! In this engaging hands-on experiment, students will connect an LED to an Arduino board and systematically replace different resistor values to observe how each change affects the LED's brightness. By writing and uploading simple Arduino code, they will learn to control the LED and monitor the impact of resistance on current flow in real time. This activity does include a worksheet for students to fill out after they have done this experiment and teachers will be provided a answer key. This lesson will reinforce key concepts of electrical resistance, and also fosters coding skills and critical thinking as students analyze their results and discover the practical applications of Arduino in electronics. Perfect for inspiring the next generation of inventors and engineers!
