I’ve been searching around for a few days… and I haven’t really found any answers…
I have an ESP8266-12F programed with the “ESP8266_Standalone”
the only editing I have done to the code is add my ‘auth’ token and set my network SSID and Password.
I have my button all set up in the blynk app and I can see when the esp comes online. I can easily turn the light on the ESP on/off by setting the blynk button to Digital gp2 but if I set the button to use Digital gp4 it immediately activates the relay as soon as I hit ‘play’ in the blynk app… and the only way to deactivate the relay is to set the app to a different gpio and power cycle the circuit.
It seems that by activating any digital gpio it then has a dc voltage of 0.2 when not active… and an activated voltage of 3.3 but apparently the 0.2v DC is enough voltage to trip my 5v DC Relay??
I was reading somewhere that I should be using Virtual pins instead of digital in the blynk app?
is this true? if so how do I Define the virtual pins? and link gpio4 to V19? because just setting my button to use Virtual pin 19 (defined as gpio4) It does not work.
So I assume I need to do some rudimentary programing! woo!
Is there a good tutorial for basic blynk program language and syntax?
I am excited to automate more things in the future and not just relays, but they can be a valuable asset in themselves
Thanks for any and all input.
if you need more info from me, just ask.
