I’ve just released an update that allows you to scroll text across the Neopixel Matrix. There are new Scratch blocks and an example in the advanced extension project that allow you to do this.
To make use of this new feature you’ll need to update your Circuit Playground Firmware to version 1.5. Any new kits purchased after this point will have that firmware pre-installed.
I’ve also made some changes to the Embedit Scratch Connection app to help make sensor reading more robust. You should see your app version as 1.7.1 now. If anyone still has sensor reading problems on the new app version please let me know.
