- hi and welcome to physical computing with Arduino in this video we're going to learn about physical computing and give an overview of the different topics
- we'll learn throughout this course let's jump in physical computing is creating or using devices that interact with the world around them think of a robot the
- robot first senses their environment thinks about the information gathered and acts based on that information a self-driving car is a great example of a
- device using these physical computing steps though this is a complicated system with many inputs and complex programs the main parts of a
- self-driving car work the same as any system will built in this course the car uses multiple sensors to detect its surroundings analyzes what this data
- means and then acts accordingly in this course we're going to be using Arduino devices to create programs that allow our device to interact with the world
- around it even though the Arduino looks simple on its own it can be connected to control multiple components and sensors that can help it note changes in the
- environment and react based on the program you've written here's an example we can use a temperature sensor to find the temperature of the room it finds
- that the temperature is 19 degrees Celsius it then thinks by applying this value to the program that has been written it sees that if the temperature
- is less than 20 a light or LED should turn on so it acts on this and lights the LED in the last example we used an if-else statement in our code you've
- probably already learned a few programming concepts such as variables loops and functions and now we'll be able to put all of those concepts
- together to create physical machines these concepts will form the foundation for how you can communicate with your device and program how it should sense
- what it should think and how it should act we're going to cover a lot of content in this course and build some awesome projects let's take a deeper
- look at all the content packs into these three modules in the first module we'll go through the basics of our Arduino such as how to light up and change the
- brightness of LEDs and learn how we use variables to make our programs more versatile we'll build our first circuits to control LEDs and motors with our
- Arduino and explore how we can use pseudocode to structure our programs from the start and comments to make our programs readable to us and others in
- the program control module and we'll learn how to apply control structures such as if-else statements and loops to create programs that will react to the
- outside world we'll build programs that use sensors to detect temperature light and distance and make decisions based on the
- information collected in the final module you'll have a chance to explore all of the capabilities of your Arduino on your own you'll research explore and
- teach your peers about new sensors follow directions to build an advanced device like those shown here and have a chance to create your very own Arduino
- machine now it's your turn to look at some awesome projects that can be built with Arduino
