The BBC micro:bit has 25 red LEDs on the front. But if you're eager for more lighting fun, Pimoroni's Scroll:bit is your answer! It adds 119 individual bright white LEDs to your micro:bit, expanding your creative possibilities. You don't need any extra components or headers. Just insert the micro:bit into the 2x40 right - angle edge connector, and you're all set. With Scroll:bit, you can use MakeCode to create graphs, animations and more using code generation blocks. Or, if you're up for a challenge, try MicroPython in the Mu code editor. Key features include a fully - assembled and ready - to - use design, a 17x7 matrix of 119 bright white pixels with individual PWM brightness control. It uses the IS31FL3731 LED matrix driver chip, is compatible with the micro:bit, and supports both Microsoft MakeCode and MicroPython. Best of all, no soldering is required! To add the Scroll:bit library in MakeCode, click the cog in the top - right corner, then 'Add Package', and search for 'scrollbit'. Full instructions can be found in the library's GitHub repository. The MicroPython library for Scroll:bit is also available on GitHub with detailed setup instructions.
Using the Pimoroni Scroll:bit is super easy. First, insert your BBC micro:bit into the 2x40 right - angle edge connector on the Scroll:bit. You don't need to solder anything or add extra parts. If you're new to coding, use Microsoft MakeCode. Click on the cog at the top - right corner, select 'Add Package', and search for 'scrollbit' to get the library. Then, you can use the code generation blocks to create graphs and animations. If you're more experienced, try MicroPython in the Mu code editor. The libraries on GitHub have full instructions to help you get started. When handling the Scroll:bit, be gentle to avoid damaging the components. Keep it away from water and extreme temperatures. There's not much maintenance needed since it comes fully - assembled. Just make sure to keep it clean and free from dust. If you have any issues, refer to the GitHub documentation for troubleshooting tips.
