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.

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!

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...

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.

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

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

Day five of #makeradvent is live and shows off a cool USB 3 micro-B to USB C adapter for those times when we need to pull data from an external USB drive. As the holiday season approaches, some relative will need some IT support, and "who they gonna call?"... YOU! buff.ly/4ioBCVo
