Treasure Hunt

1- We all may found something in our life it could be precious, and it might be not but for sure we built expectations if we found a real precious thing.

2- Treasure hunt is the game of every child, as we are looking for the precious thing that would bring our life up.

3- We have to play the game as a team that each one have his own role to play.

4- What role you are good at ?

5- Now let’s play a quick game together.

6- Emoji Scavenger hunt is an online game that uses the camera of the smart device to let you capture the thing been asked for in the game.

1- The version we are going to build is hardware based, but we have to code each microcontroller in order to do the needed job.

2- Lets start coding the microcontroller.

3- To code we have to access the make-code platform, then we have to redirect to micro-bit version.

4- Then we have to create new project and start coding the microcontroller.

5- At the beginning we have to understand what is meant by loops and the different between each loop and another.

• The platform comes with On-start loop and forever tool at the start.
• On-start is the loop that going to be executed at the start of the microcontroller.
• Forever loop is the loop that are going to be executed as long as the microcontroller running.
• There is other also like while condition loop which is going to run as long as the condition is true.

The Video will show the importance of having loops in coding.

6- Then we will start explaining the importance of Variables.

7- Then we will describe the radio communication and how it works.

8- Radio communication is about sending information over a frequency of wave and receiving over a frequency of wave.

9- In micro-bit we have a group for the radio and power that we can control.

10- In our game, we have a transmitter and also a receiver; the transmitter is going to be the object we want to hide, and the receiver is the device we will use to discover the object.

11- For each transmitter we will assign an ID to send, it could be a number that being sent over a period of time for other receiver to catch it.

12- In this case, we decided to send every 200ms.

13- Then for the receiver, we will set the radio group to match the transmitter in order to receive the message.

14- Now when ever we receive a communication over the radio channel which is (1) in our case It’s going to be printed on the screen.

15- Now we can hide the transmitter and ask the participant to start looking for it.
