This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will use physical computing to explore the concept of selection. Pupils will use conditions to control the flow of a program. They will make use of their knowledge of repetition when introduced to the concept of selection and write programs that utilise this concept.
Lesson Summary
You will learn to write a program which uses multiple outputs.
Key Notes
- Multiple output components can be connected to a microcontroller.
- Count-controlled loops are used to produce specific outcomes.
- An infinite loop is a sequence of instructions that is continually repeated.
Vocabulary To Learn
- motor: a machine that converts electrical energy into mechanical energy
- count-controlled loop: a chunk of code that repeatedly runs a section of the program a certain number of times
- algorithm: a precise set of ordered steps which can be followed by a human or a computer to do a task
Common Mistakes To Avoid
- The motor must be wired in one specific way to work.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Multiple output components can be connected to a microcontroller. Count-controlled loops are used to produce specific outcomes.
2. Define this computing term and give one practical example. 'motor'
a machine that converts electrical energy into mechanical energy. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The motor must be wired in one specific way to work. Correction: It will work in both directions, but reversing connections changes spin direction.
