Combining outputs
Lesson details
Learning outcome
I can write a program which uses multiple outputs.
Key learning points
- 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.
Keywords
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 misconception
The motor must be wired in one specific way to work.
It will work in both directions, but reversing connections changes spin direction.
Teacher tip
Ensure you can confidently connect Sparkles and motors to the Crumble controller so you can model this clearly to pupils using the software.
Equipment
Pupils will need access to a microcontroller, crocodile clips, battery packs, motors and printed paper dancer discs. Examples in this lesson use Crumble https://oak.link/crumble

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
