In this tutorial, you will get to know the Robo Code App interface and basics, as well as create your very first Code project.
There are 3 Robo tabs to check out:
Welcome to your Coding Screen or canvas, here you can find different buttons & icons.
Actions - Coding icons which look like bubbles and perform an output task. There are 4 types of Actions in the Action Dock – Sounds, Visuals, Movement and Specials.
Attach new Modules - RGB Light and 2 Motors to the Main Block to the Main Block to see Visuals and Movement Actions available in the Action Dock.
Drag & drop the first Action on the canvas. It appears with a Start Point on it. Drag more Actions on the canvas.
Tap on an Action to adjust it. Different Actions have different Settings. Sounds don’t have any settings.
Press the Connection Button to activate the Connection Mode and draw an arrow from the first Action to the second and third. Tap anywhere on the canvas to deactivate the Connection Mode. You created two Connections.
Pay attention to the direction of the arrow you draw to avoid a mistake in the code.
Press the Trash Bin button to enter the Delete Mode and delete the wrong Connection by clicking on it. Tap anywhere on the canvas to deactivate the Delete Mode.
Once your code is ready, press Play Button to start the program. The green circle will indicate what part of the code is executed now.
You can stop your code any time you need by pressing the red Stop Button.
To execute multiple Actions at the same time, drop one on top of another. This big bubble is called State. Test the program to see how it works. You can combine up to 5 Actions in one State.
Please note: It’s not possible to combine actions that use the same module into one state.
You can move all Actions and States around to arrange them how it’s more comfortable for you.
To make an infinite loop, connect the last state to the first so that it forms a continuous flow.
The first Action that you drop on the canvas has a Start Point. It means your code starts here. You can move the Start Point from one Action to another.
Triggers are coding icons which look like red stickers and have to be placed on the Connection between 2 Actions. Triggers are conditions that regulate if this Transitions between 2 Actions happens.
Drag & drop a Counter Trigger on one of the Connections.
Tap on a Trigger to adjust its settings. Different Triggers have different Settings.
Try out a Counter Trigger by running your code. The Counter Trigger regulates how many times the Transition will be executed, so it is needed to create a Finite Loop. It means that the code will stop after the Transition was repeated 2 times.
You can combine two triggers using AND/OR logic. Here we will try the AND logic together and you can learn more about Triggers in the next tutorial here.
If two Triggers are placed in the AND mode, both of them need to occur (=to be TRUE) for the transition to happen. Add a Timer Trigger to your code and change the settings. Now the Transition will happen 2 times and each time in 3 seconds.
You just created your very first Code project!
Press the Save & Exit Button to exit to your Coding Lab, your project will be saved automatically.
