Did you ever upload a sketch and forgot what it was supposed to do? Forgot the pin assignments or the programme that it contains?
I trust all of this can be fixed with a simple API
The first API attempt can be seen in tcs34725_ginscope.ino at https://hackaday.io/project/19913-spectro-scopy-metry-graphi-cally-ginscope All suggestions appreciated!
One can always check if incoming payload is json object or custom data, allowing for custom data structures or if speed is not an issue, one could even pump the data in JSON format too
