Ozoblockly is like Scratch, but for robots. Here, you get to program Ozobots directly without color codes.
The first thing is to go to: https://ozoblockly.com/editor?lang=en&robot=evo&mode=2 and then click on Get Started on the lower left.
You can read the tutorial if you like (click on OzoBlockly Tutorial) or dive right in. I don't like tutorials, so I dove right it and clicked Get Started.
