This doesn't quite sound like a "Beginner" project when you haven't seen Ev3 programming before. As far as I can tell, this is the equivalent to variables in RCX code.
Isn't that just a math block? =-0
No, in the EV3 software, that is the image of a default my block before any modification. It is hard for me to get the pictures with the software i am using to edit photos, so i decided to use a generic picture i only have to take once as opposed to a new picture for every new my block. But once again no that is not a math block.
This is a very helpful my block, you can chose a number, an increment/decrement value, and weather to increment or decrement the number.
