Crack the Code for Arduino - Control Technologies

Hello and welcome to the ‘Teaching Crack the Code with Arduino’ course. My name is Madeleine Schappi, co-founder of Little Bird Electronics. We were the first to bring Arduino to Australia and have been running Arduino courses for more than 12 years. In this course we take our Arduino know how and apply it to the Australian syllabus aligned Crack the Code Unit of Work. If you’re new to teaching with Arduino and wondering how to get started, this is the course for you! Control technologies are everywhere. You have probably already used plenty of them at home, school or at work. In this lesson, let’s take a look at what are control technologies, what they’re comprised of, and how you can identify and explain examples of control technologies to your students. What is a Control Technology? First, let’s examine the definition of a control technology A control technology is first and foremost, a system that controls and monitors. This is done through a sequence of instructions that has been programmed on the system. In other words, it is a system that has been designed to perform tasks which may include responding to the external environment. Some examples of control technologies include: a television remote control, an air conditioner and traffic lights. Can you think of some more examples of control technologies? Pause the video now, then list three more examples that you can think of before resuming the video! Did you think of some examples? What does a furby toy, a robotic floor sweeper and a washing machine have in common? That’s right, they’re all control technologies. Take a closer look at each of these systems and you’ll find that they are made up of common components. These components can be classified as either sensors, actuators, or processors. Disassemble a television remote control and you will find inputs, actuators and processors in it. The buttons are the inputs, and remember, input signals are manipulated to get the desired output result! In this case, that would be the changing of channels. This is done through infrared radiation. Look at the printed circuit board, the microprocessor is found on it. There is also an infrared LED. This can emit a beam of infrared radiation that is then detected by a small infrared light detector on your television set. So the infrared LED is the output. In the next part of this course, we’ll be taking a look at microcontrollers, and their role in control technologies.
