This weekend I spent some time figuring out how the Barcode Detection API in Chrome on Android works, and implemented a basic barcode scanning web app. I hope to integrate with some kind of food database, so that I can easily track what goes in and out of my pantry.

I also played around with the Circuit Playground Express I got for free with my Hackspace magazine subscription a while back, specifically using it as a colour sensor. I ordered some crocodile clips off eBay so that I can also play around with the soil moisture detection example.
