I’m trying to use a esp-01 with relay module to do stuff. Right now it will just turn a led on and off on my bread board but if I get it working then I will adapt it to do other things. Right now I cant get the Blynk app to control the relay.
Some common troubleshooting questions:
What board and module?
The app is setup with ESP8266 board.
-according to everything I can find the GPIO2 pin is the one that controls the relay, i have confirmed with a 3.3v+ directly wired to the pin.
-I can post the code if needed but I was using the example for esp8266 wifi in the blynk library.
The board boots, and the Blynk app connects to the board, but the buttons dont work. My button is a digital gp2 button switching between 0 and 1.
Any help will be greatly appreciated. If the answer is already out there I’m sorry I searched and searched and i couldn’t find anything with this board and this module.
P.S. I know this can work i have seen it in person. Unfortunately I have no way of contacting the person who showed it to me.
