Dr. Kenneth Wong, together with Dr. Anthony Tam, organized a 3-day STEM workshop at La Salle College in December 2019. Over 20 students from junior forms attended this workshop, in which they learned how to build a 3D-printed tank with an infra-red battling system and program the Arduino board for controlling the tank using a mobile app via Bluetooth. Participants found this workshop very enjoyable and enhancing their interest in Computer Science.
