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

Yep

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

Playing catch the @microbit.org @4tronix.co.uk #mini:bit !! WHY ??? Because we can . . .

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

What’s it doing, or not doing?

Thank you @4tronix.co.uk So lovely to see you over on this platform. This stream you've posted has made me more than certain that I need to upgrade from your #BitBotXL I bought myself in 2023 to the #BitBotPRO Your #BitBotXL is still a great buggy for teaching 11-14 year olds introductory robotics.

Email sales@ please

Anyone working with BBC micro:bits - I'm really enjoying working with the robo:bit mk3 from @4tronix.co.uk.

So easy for students to use, enabling them to go from zero to seeing their code control a robot within an hour session!

This is a #RaspberryPi and CamJam event at the William Gates Building in Cambridge on Saturday, 1st March. Come along - it's always a lovely time with like-minded people!

In the Javascript window, click on the Explorer tab on the left and scroll down to see the BitBot version. This image show 2.1.13. You can click on this to refresh the extension to the latest available.

For BitBot PRO, always make sure you are using the latest Makecode extension as we often make improvements to functions and accuracy. The latest release 2.1.13 improves soft starts in order that the wheels don't slip as much and give misleading information. shop.4tronix.co.uk/products/bit...

Draws an octagon by calling a generalised function for drawing polygons

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:

Draw a hexagon by repeating 6 times, and turning 360/6 degrees each time.

Using BitBot PRO to draw polygons: Part 3
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:

Draw a square by repeating four times the operation of drawing a line and turning 90 degrees

Using BitBot PRO to draw polygons: Part 2
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:

Draw a line then turn 90 degrees. This is 1/4 of a square

Using BitBot PRO to draw polygons: Part 1
Because BitBot PRO can move and turn accurately, we can use it to draw geometric figures. Let's start with drawing a square. We first have to draw one side, then turn 90 degrees. Like this
