esp8266 + arduino + ubidots
Posted: Mon Jun 08, 2015 11:59 amgreetings.
not sure if I'm posting at the correct section but here goes;
I'm trying to get photosensor reading on Ubidots.
I've updated the firmware of the Esp module and the following;
I got this on my serial monitor and it just stuck like so;
Any idea why is it so?
thanks in advance.
