This resource was created by Alistair Barker (

First, they pair up and complete the sheet below to agree on the pattern of 1’s and 0’s to represent an A or E, etc. They also need to agree on patterns to encode the protocol part – “are you ready to send?”…They play the role of sender and reciever, getting together afterwards to see if they sent the intended message.
