LEGO MINDSTORMS EV3

A robot that contains balls and releases them. It counts how many balls to release depending on the "treasures" it has hunted on the field. This is part of the World Robotics Olympiad 2015 Elementary challenge. 

When programming people try to reuse other programmers code. Either because that part of their project is too complicated or time consuming or because there is no need to write code, that it is already written. That allows you to focus on what matters. In our case in order to reuse code from one project into another we need My Blocks. Now we will take a look at how we can import a My Block in our projects.

In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")  

Continuing with the Proportional algorithm for following lines. Smooth and stable this is the first part of the PID.
