Tell us about yourself!
Hi you wrote GPIO5 to GND but on the pic GPIO15 is grounded?
I went with D12 and for small work I can use my ILS tip :)
So I got t12-ILS which as you pointed cant be used for larger elements. Can you suggest a replacement? B or D series? I was thinking about T12-B2Z ?
wow thats awesome
wait a minute, you can just use ESP8266 module for that? It has GPIOs to which you can connect the temp probe and has even more memory than arduino to put your soft there, am I right?
