There is a project with 4 buttons and a relay, everything works, but I want to add another physical button that will turn on and off all the relays at once. I tried to do it myself, and it works, but with a mistake, I lack experience or knowledge … please help me.
The button works on and off, but after the remaining buttons work from the second press.
Project on Esp12F and Arduino IDE
And another question is why if I add pin 9 to the code (ledpin5) esp constantly reboots?
