Crumble Sparkles and Switches – Pelican Crossings
Make links to every-day objects and engineering using the Crumble controller.
The crumble is a programmable board that can drive a range of components and take in sensor data that can be used to change the behaviour of those components.
See how we have used the crumble to make traffic lights using LEDs called sparkles that are activated in sequence using a switch.
Students learn about circuits and how to connect the components to the crumble board using crocodile clips. The board is then programmed using Scratch inspired block-based coding. Once programmed the USB lead is disconnected and the project is ready to test.
Using the switch kicks off the sequence of code that has been programmed onto the crumble.
Linking to how pelican crossings are used in the world around them really brings the learning to life. Challenging learners to think about how traffic lights are used and controlled, alongside changes that may be made for different environments.
What might happen if the time taken to change from green to red, or back again is too fast or slow?
Using these physical computing approaches, students learn quickly and are driven to want to be successful. Failing is fun and there is always something to learn from these failures and apply to the next test.
By using other physical materials students extend their learning by seeing how to deploy their traffic lights and also how to adapt the sequence using sensors.

Developing Engineering Habits of Mind such as problem finding and solving, visualising and adapting is a common thread throughout our workshops. Alongside developing planning, communication and teamworking skills we also link out to real-world issues and uses.
Often our learners are really creative and come up with novel ideas that stretch our thinking and those around them!
We are back with Skill Clubs in Sandbach and Northwich this Summer. The full timetable of all the STEM activities we are getting up to can be found on our Skill Clubs page. There is also lots of info about the sorts of things that happen at each club, how to book and our updated Covid-19 policies […]
We send out newsletters that are linked to your interests. Our work is quite wide and varied so one newsletter doesn’t always suit everyone.Let us know what you are interested in on the form and we will send you the relevant information and news from us. Don’t worry we won’t spam you with lots of messages […]
We are really glad to be able to celebrate being in business for 7 years with Skill Supply.
