Depends what you mean by "breakout boards". We have a number of accessories: shop.4tronix.co.uk/collections/...

Probably means you should swap your 1s and 0s

Not quite. The second clause should have left? Line sensor compared with zero not one. Also you need a pause each time round the loop so the PWM can work correctly. Say 20ms or so

Yes. Well it’s actually a prototype! Version 0.2

Does it work okay if you change it as suggested?

Anyway you shouldn’t do all that in the Start block. Put it in a separate Forever block. Should work then

Using BitBot PRO to draw polygons: Part 4
Now we can generalise by creating a function that takes two values: number of sides and length of each side. This example draws an octagon by specifying 8 sides to the function:

we can then generalise the square to any number of sides by changing the number of repeats to the number of sides required, and the angle to turn to be 360 divided by the number of sides. This is valid for all numbers greater than 2. A hexagon has 6 sides:

To complete the square we need to repeat this operation 4 times, once for each side (or once for each corner).
So let's use the Repeat loop built in to Makecode. This code will draw the full square and leave the BitBot PRO where it started:
