Control ToyCar over Web


I’m new so bare with me!

I need guidance on my project. I want to control a ToyCar from a web browser otside of my ToyCar Wifi. I want to do this either from Keypresss in the webpage or on-screen clickable button.

I am using a Arduino UNO. Also ordered a ESP8266

Have I understood this correctly?:

PC with Internet will write to —> MySQL (to hold values) —> Arduino will read these values to go HIGH or LOW.

I’m still in planning mode to understand what to be focusing on. Is this a correct way?
