We have just created a new resource for the Micro:Bit, one based on Morse Code. This is a simple activity, but it has plenty of humanities spin offs, especially with regard to the local curriculum. For example, where was the local telegraph station in your neighbourhood, who where the coders, who were the runners, when was the last telegram received in your town etc.
In addition, there is a good case to say that Morse Code is a binary code and the network it spawned was an early version of the Internet. Apart from anything else, sending Morse Code via a Micro:Bit is easy and fun, a simple entry into explaining how data is moved around the internet today and in the past, using binary codes.
If you are not too sure how the coding for this project should work, we have created an example at Make Code for you to use. Just click on the link to be taken to the shared resource. Obviously this is a resource to support teachers and not to be shared with students, good luck and have fun!
If you want us to make more of this kind of resource please contact us at firstname.lastname@example.org and we will make more resources to share with you, related to your need. If you want to gain access to a copy of the teaching resource shown above please contact us also.
