Wemos D1 Mini/ESP8266 based smartphone controlled car DIY for less than $15
UPDATE: I have posted the write up on my blog. https://automatedhome.party
I made this over the past week. I will be creating a write up on how I made it along with the code in the next week or 2. I will post it on my blog at https://automatedhome.party
The joystick is via a webpage hosted on the ESP itself. No need for a separate app.
This was a lot easier to set up than I was expecting. The hardest part was getting the joystick to work and the actual construction. If I were to do it again, I would probably use a kit for the car.
If anyone has any questions about it in the meantime feel free to ask in the comments.
