Lesson Three focuses on programming. In this lesson you will learn:
Why we use digital technologies
About programming and bugs
To do some programming
The driving force behind digital technologies
Humans have used technology to come up with ways of improving their lives. How many things can you think of that you have used today that use digital technology?
To create the technology behind the Electric Garden, Rob the programmer wrote instructions for the Electric Garden. The instructions mean that the raw data collected by the Electric Garden is output as easy-to-read data on our devices (for instance, it shows us when soil moisture is getting low). We then analyse and use that data to grow larger vegetables! Rob’s instructions were in the form of code. This is called programming.
What is debugging?
Sometimes we make a mistakes in our programming that cause problems. These are called bugs! We can debug a program by finding and fixing the mistakes! The short video shows an example of a bug and how they fixed it.
