Lesson details

Learning outcome

I can use a microcontroller to design and test a control system.

Key learning points

  1. There are different languages to programme a microcontroller; they might be text-based, use blocks or flowcharts.
  2. Input, process and output are the basic features of a control programme.
  3. Feedback can be incorporated into more complex control systems.

Keywords

  • Microcontroller - used to control outputs by processing inputs

  • Programmable - provide instructions to complete certain tasks

  • Flowchart - a simple diagram using symbols to show steps in a task

Common misconception

Control systems are programmed with text-based languages.

Control systems can be programmed using different languages including text, blocks or flow charts.

Teacher tip

When using Tinkercad, create a Class List and share 'Nick Names' and 'Classcode' to your students. You could also allow pupils to log in if they have a Google school email address. In Tinkercad, it's good practice for pupils to rename the file before they begin.

Equipment

Student access to Tinkercad website.
