Thanks K that’s great!. I actually bought the Breakout Garden mini for an indoor air quality set up so I can put the AQ set-up back together. It’s got a BME680 Volatile Organic Compound breakout and an 11 x 7 matrix on - and it has a smiley face which turns to a blank face when the air goes bad, ie. when
the AQ score goes below a certain percentage. It’s one project I loved doing because I learnt so much python from it!
