+To program this example you need to use the buttons, the matrix and the messages.
+==== Programming ====
+You can program the wristband progressively. For each step, add the displayed blocks and put them in the right order. You can then test your program by clicking on {{:en:instructions:play.png?direct&30|}}.
+=== Step 1: Showing an image when a button is pressed ===
+  * You will say to Kniwwelino: « //If I press button A then show my image// ». Use the following blocks and add them to Kniwwelino loop forever:

+=== Step 3: Instead of showing images on your matrix, send them to your friends ===
+  * Create a group for your friends with a secret name like  «  mySecretFriends ». Only your friends, using the same name as you, will be able to exchange messages with you. You will say to Kniwwelino : « //Send my messages only to those Kniwwelinos who use the same group name as myself// ». Use the following block at the beginning of your program:

+{{:en:instructions:wristband06.png?direct|}}
+  * Send the images to your friends. You will say to Kniwwelino: « //Send the images to my friends// ». Delete the violet matrix blocs and replace them with orange messaging blocks.
