How to Code
In this example, BYOB will be used. Use this in BYOB:
when I receive [ascii for letter v] set [ascii v] to (ascii for ([letter v] sensor value)) broadcast [ready v]
Save that as plugin.ypr. Now use this in Scratch:
when gf clicked forever ask [Letter:] and wait set [letter v] to (answer) broadcast [ascii for letter v] and wait end when I receive [ready v] set [ASCII v] to ([ascii v] sensor value)
Save that as connect.sb.
Now, connect BYOB and Scratch using Mesh and start connect.sb. Enter a letter. The variable
(ASCII) will contain the ASCII code.
