LESSON 15: Controlling LED Based on User Input From Serial Monitor

This lesson demonstrates how to create a user-interactive program using the Arduino, focusing on obtaining user input through the serial monitor and performing different operations based on the input. Here’s a brief overview of what you will learn:

  1. Reviewing Previous Homework: Recapping the assignment from Lesson 14, which involved controlling the brightness of an LED by getting input from the user on the serial monitor.

  2. Setting Up the Circuit: Instructions on how to correctly connect an LED and a resistor to the Arduino, ensuring that each component is properly configured for the experiment.

  3. Writing the Code: Step-by-step coding instructions to read user input from the serial monitor and use it to adjust the LED’s brightness. This includes mathematical calculations to translate the user’s input into a value that the Arduino can use to control the LED brightness.

  4. Exponential Scaling: Explanation of how to use exponential scaling to ensure that the perceived brightness of the LED increases smoothly across the range of user inputs.

  5. Debugging Tips: Guidance on troubleshooting common issues such as incorrect readings or errors in the output that affect the LED brightness.

  6. Homework Assignment: creating a program that asks the user for a brightness level (between 0 and 10) for an LED and then sets the LED brightness accordingly.
