Moving around with Scratch cat and show colors on SenseHat

SenseHat and Scratch 3

I wanted to try something with my SenseHat again. When I discovered that Scratch3 has building blocks for the module, I thought of using the joystick to bring The Scratch Cat to different colour fields and then have the matrix light up in the same colour.

A simple test and some preparation

To test the connection between Scratch and my SenseHat first, I wanted to display the temperature by pressing the joystick:

and it works:

For the right design of the movement I mirrored the two costumes of Scratch-cat.

Now, we paint some circles in different colours on our stage

Movement up and down

When we push the joystick upwards, Scratch-cat also moves upwards on the stage. The same happens when we press the joystick down, Scratch-cat then moves downwards. For now, we ignore the broadcasts, we use them later.

Movement left and right

This is quite similar, but we need to change the costume of Scratch-cat.

More realistic movement

To make the movement of Scratch-cat more realistic, we now create the broadcast for "move".

Colour "sensing"

The last part is for the "colour sensing". As soon as Scratch-cat touches a colour field, the SenseHat should light up in the same colour. If the colour field is left, the lights of the SenseHat also go out.
