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
- Physical computing involves creating systems that interact with the real world using software and hardware.
- Microcontrollers are small programmable devices that can control electrical components like LEDs by running simple code.
- General purpose input output (GPIO) pins are used to interface with the real world.
- Embedded systems are used in a wide variety of applications, from consumer electronics to industrial machines.
Keywords
Physical computing - using code and electronic components to interact with the physical world
Microcontroller - a small computer on a single chip that’s designed to control simple devices and systems
Embedded systems - a computer built into a device to perform one specific task or a small set of tasks
GPIO pins - connection points on a microcontroller that you can program to send or receive signals
Common misconception
Physical computing is just about programming robots.
Physical computing is much broader than just robotics. It includes any system where a computer interacts with the physical world through sensors and actuators, for example wearable devices, environmental sensors and smart home devices.

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.
