Doh- should have read the description properly: 

“The Arduino NANO Every has the standard ADC and PWM resolutions of 10-bits and 8-bits, respectively. This board doesn't have PWM on D11 and therefore it supports only 5 PWM outputs, as on the Arduino UNO WiFi Rev.2. “

and guess which pin I used for the LED- yep- D11 🤦‍♂️

Still good to know why it’s not working and should be easy enough to fix

Moved it to D6- that did the trick.

think it should be strong enough 

Very cool. Congrats! Rob
