- Mon Jun 12, 2017 1:17 am #67033 Greetings,
I have run into a problem when combining the neopixel library and BasicHttpClient, But when i combine them i cant get the neopixels to work. The the http client works as expected, and the neopixels work when not combined with the BasicHttpClient

The only thing i need to have done is the color of the neopixels set based on the parsing of a webpage.

I have no real idea what is going on

I use an 74HCT08 and gate for level translation.
