Lesson A-15:
Nested If Statements & String/Integer Conversion
In this lesson you will continue to use logical statements in your Python code by adding increasingly complex criteria to your if statements by nesting the statements. Then you will learn to work with both strings and integers in your code.
Working with Nested If Statements
Strings vs. Integers
Writing a Python Game Program
Lesson B-13:
Level Shifting &
Infrared Sensors
In this lesson you will learn how to shift the signal level so your Raspberry Pi can work alongside 5V devices. Then you learn how to work with an infrared obstacle sensor and an infrared line sensor.
Signal Level Shifting
Infrared Obstacle Sensors
Infrared Line Sensors
Lesson C-6:
Working with Audio
In this lesson you'll learn to incorporate audio into your Raspberry Pi and Python projects. Concepts taught include how to use an amplifier in your circuit, how to work with the various audio output options, and how to write the code needed for audio functionality.
Adding Audio & Using an Amplifier
Audio Output Hardware
Working with Audio Code Commands
Lesson D-11:
Robot Motor PWM & Calibration
In this lesson you'll learn to control your robot's motor speed using pulse width modulated signals which allow for moderated speeds in between the 0% and 100% speeds allowed by the Raspberry Pi's high/low digital signals. Moderated speeds are useful for making turns and following a line course.
