MyBlock - functions

Find "My Blocks" in the menu, here:

Click "Make a Block" to create a block (function). 

Here's an example sketch.

You can copy the sketch, or download this file,  then open it with  Codecraft using  "Files ... Open local projects"
Blink_MyBlock.cdc

 I created a block called "blink."
The block (function) takes 2 parameters:

• how_many (times to blink)

• how_long (to delay between the LED on and off time)

Then, I used the blink block in the loop function of the sketch.

If the button is pushed, blink 5 times with a 100 msec delay.

Take a look at the Arduino code that Codecraft generates to see how functions are declared in the Arduino language.
Click on "</>" on the upper right  to see the generated  text sketch.

The details for Arduino functions are in the
Arduino Language Reference - FunctionDeclaration

"Segmenting code into functions allows a programmer to create modular pieces of code that perform a defined task and then return to the area of code from which the function was "called". The typical case for creating a function is when one needs to perform the same action multiple times in a program."

Note:
My Blocks known issue:
Text input parameters are not working.
Only numbers and boolean inputs in this release of Codecraft.
