I´m new here and relatively new to Arduino and everything having to do with programming.
I can´t find a solution to switch between 3 relays by only pressing one button.
I have a 4 Relay Module connected to a ESP8266. The 1st relay will be used to switch the fan on & off
(I´m fine with that - that´s pretty easy) but... the second button should alternate between relay 2 - 3 and 4 in a loop.
2nd relay 1st speed
3rd relay 2nd speed
4th relay 3rd speed
Fan Speed 1 - Press button - Fan Speed 2 - Press button - Fan Speed 3 - Press button - repeat.
I have downloaded several libraries and tried to work my way trough, read a couple of articles and searched the web, but I somehow can´t figure it out. Can anyone help?
Project.: I´m working on a wireless Fan-speed controller controlled by Blynk-App
I have already designed a remote control via the Blynk App for my little weatherstation I´ve build.
Its monitoring Temp, Humidity and Lx-intensity. giving me output on a little 128x64 Oled-screen and transmitting data to the phone.
That´s basically everything I´ve done so far ^^
Thank you everyone!
