Hello. I am fairly new to the Arduino world. I have messed around with multiple boards and have done most of the experiment projects. I have even written some code, nothing crazy at all.
I am looking to develop an app for my IPhone that I could control a servo and relay connected to an Arduino ESP32.
I have absolutely no experience with creating apps. Where could I start to educate and hopefully be able to make this happen? I am looking for any type of books or websites for beginners. I did some research but was able to find much. Any help would be great!
