These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Motors convert electrical energy into motion.
- Microcontrollers cannot drive motors directly.
- Motor drivers are needed to safely control motors.
- The direction and speed of motors can be controlled with code.
Keywords
Pin - a physical connection point on a microcontroller, microprocessor or electronic component
Ground (GND) - acts as the return path for electric current and is essential for a circuit to work properly
Motor controller - hardware that takes signals and manages how a motor behaves
Library - a collection of pre-written code that you can use to make programming easier and faster
Common misconception
You can connect a motor directly to a microcontroller and it will work fine.
Microcontrollers send control signals, not power. Motor drivers act like electronic switches to take a signal and safely drive the motors with their own power supply.

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.
