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
