Im just going to throw out bullet points. I could figure this out myself if I had more time, but I dont.
-
4 buttons on a keypad need to be pressed individually (solenoid or servo)
-
Needs to be activated remotely (web interface & app)
-
Currently using ESP8266 and Arduino UNO with Shield
I can get the hardware sorted no problem. The coding is where I am stuck.
Please contact me if interested.
