Two Year 10 Engineering classes attended one day event at La Trobe university to work with experts to learn Arduino. Students worked towards creating a dexterity game with the use of LEDs, LDRs, potentiometers and an Arduino Uno. Students were engaged in hands-on STEM education to develop 21st Century skills. They exercised problem-solving skills, whilst programming and assembling hardware to solve problems related to real-world ideas. A visual programming language; Snap4Arduino was used throughout the day.
