Display Array Blocks

This is an EV3-G block for displaying the values of array cells in an EV3-G program.


The project contains two programs, which are demos of the blocks for displaying Boolean and numeric arrays.

Two blocks

You can import that blocks in your programs. They are designed to show you in real time what are the values in your array and let you go to the next bit of your program. The blocks operate with the UP and DOWN brick buttons to iterate through the array. And the CENTER brick button to advance to the program.

The blocks are very useful for students to show them in real time what values they have stored in their arrays. Because there is no easy way to see real-time what the values are in the array even if it contains only a few elements.

The block shows you how many elements there are in the arrays and the values in the following way:

For Numeric

For Boolean
