Physical computing

Curriculum > KS4 > Unit

This unit introduces learners to physical computing through six lessons and culminates in a finished working robotic buggy. Learners use a Raspberry Pi Pico microcontroller to explore inputs and outputs, and utilise a range of hardware components, including motors, reflective optical sensors, LEDs, and an ultrasonic sensor. This unit of work allows learners to practically experience the use of embedded systems in support of the GCSE computer science specifications.
