The Organisers reserve the right to recover the cost of the workshop(s) and the cost of material(s) should the team drop out of the Challenge after attending the workshops and receiving the IoT:bit Kit and/or the project tool(s).

Workshop 1 Introduction to micro:bit and Cyber Security 

Duration of workshop: 2 hours 

Medium of instruction: Cantonese 


In this workshop, you will learn how to use your micro:bit’s radio and broadcast communication 
function. One of the salient features of micro:bit is that it can send messages to all micro:bits. You will  establish wireless communication and configure the micro:bit radio to understand the concept of broadcast and broadcast address through receiving and sending different message types (such as a number or a  string) using radio broadcast.

After mastering the radio function, you will also explore the concept of Cyber Security and engage in 2 activities, setting the password of your own micro:bit and unlock/hack the password. 

Activities covered for this workshop: 

• Program Sequence - Use button to display images with pause and simple animation
• Variable – Rock-paper-scissors or dice roller

• Loops and Conditions - Step counter using accelerometer, LED plot with animation 

• Radio – Sending and receiving messages, setting groups, broadcasting
