You're safe within your enclosure! But there's no mobile phone signal and the landlines don't work. How can you communicate with other groups of survivors? You need to send some vital messages soon!

Your task:

Create a transmitter and then send and receive your vital messages - in code!

Your club leader will explain what kind of transmitter you're going to build

1. Build and test your transmitter by:

building a circuit to control a lamp
or using a morse code app to control your phone's flash.

2. Practice using Morse code so your dots and dashes are clear and there's a pause between letters.

Practice words: Hello Morse Virus

3. Take it in turns to send a message between teams! How fast and accurate can you get at sending, receiving and decoding the messages?

Try sending the following messages:

Medical emergency - send first aid
25 zombies coming take cover
Urgent need food and water

Think of your own message to send to another team.
