Codebug is great fun, the Blockly programming is more challenging than Scratch but that is ok.
As a test a Codebug was used to control two glowbugs (see http://www.codebug.org.uk/learn/activity/74/glowbugs-wearables/#step446 for more details on Glowbugs and working with them on the Codebug).
Set the Glowbugs 0 and 1 to yellow;
Scroll a message across the 5x5 grid saying yellow;
if button A is pressed
Set the Glowbugs 0 and 1 to red;
Scroll a message across the 5x5 saying red;
if button B is pressed
Set the Glowbug 0 to blue;
Scroll a message across the 5x5 saying blue;
