4tronix @4tronix.co.uk · 24/06/2025Depends what you mean by "breakout boards". We have a number of accessories: shop.4tronix.co.uk/collections/... 010
4tronix @4tronix.co.uk · 10/06/2025Not 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 210

Reposted by 4tronixAllen Tsui @compscitsui.bsky.social · 13/04/2025Thank 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. 031
Reposted by 4tronixPeter Gallivan @petergallivan.bsky.social · 22/01/2025Anyone 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! 031

4tronix @4tronix.co.uk · 18/01/2025For 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... 041
4tronix @4tronix.co.uk · 14/01/2025Using 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: 010
4tronix @4tronix.co.uk · 14/01/2025Using 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: 110
4tronix @4tronix.co.uk · 14/01/2025Using 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: 100
4tronix @4tronix.co.uk · 14/01/2025Using 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 110
