STEM Workshops

This cutie, only four and a half years old, successfully completed our Electronics Prototyping Workshop! We always love to see the expression on our student's faces when the two blue LEDs start flashing. They can't believe they made it work and can't wait to show mum and dad.


Electronics Prototyping Workshop - Job Done!
