Timer + Button with same pin

FAQ
1

Hi. I’m new with arduino + Blynk for a month. I need to ask a question. I use Button to trigger pin D2. D2 trigger a relay to on/off a lamp. I need to set timer to on/off lamp in fix time every day. Can Timer do that? I try Timer and it need to trigger another pin, can Timer use same pin D2 with button?
I has a Gsm shield, can this shield work with Blynk?

thks so much

Hello.

You can’t assign both widgets on same pin. But you can do that via Virtual Pin.

@vshymanskyy should know better.

GSM shield could work with blynk, but currently you can only use HTTP API.

UPD: this is no longer true: GSM is supported by Blynk natively.
