This educational tool is designed to illustrate the behavior of variables in RAM memory.
Each box features a window with a label displaying the variable name and a plate to hold the variable's potential value.
Variables are distinguished by their unique data type, format and color.
The RAM memory, represented as a cabinet, is divided into sections each holding 8 bits of information. Placing a box into the cabinet aligns it with a specific memory address, indicated by an arrow.
For reusability and easy value replacement, the plates are covered in plastic and compatible with board markers.

The char variables, depicted in blue, have magnets on both sides to allow them to form strings.

There are boxes larger than others but with the same shape. This suggests to students that smaller values can lead to wasting space and inefficient use of RAM memory.

Code exercises can be done in pairs. One student takes on the role of code interpreter, while the other acts as the user, guiding the code's execution using a "console interface" and writing values to the variables in RAM memory.
