Wifi RC Car ESP8266

Lacour Vincent

About this app

✴ This application allows you to control a RC wifi car using your smartphone.

✴ To create my Wifi car, I used the NodeMCU V3 microcontroller which includes an ESP8266 Wifi module. The car can be controlled either in AP mode (Access Point) or in STA mode (Station).

✴ The steps to control your car are:
• connect your smartphone to the same wifi network as your wifi car.
• Make sure that the application parameters are correct (IP, PORT, etc..).
• Have fun!

✴ 3 different ways to control your car:
• buttons.
• accelerometer.
• voice.

✴ List of default commands sent to your car server to control the motors are :
• http://IP:PORT/move?dir=F (Forward)
• http://IP:PORT/move?dir=B (Backward)
• http://IP:PORT/move?dir=R (Turn Right)
• http://IP:PORT/move?dir=L (Turn Left)
• http://IP:PORT/move?dir=S (Stop)

• http://IP:PORT/action?type=(1-8) (Action 1 to 8)

Ratings and reviews

Very nice and working I had an old RC car and a WeMos D1 mini and had to do some changes to the code, just 4 words! As I had one motor for steering and one for acceleration (I just had to change the HIGH and LOW settings of the pins). Otherwise this code will work for SMARS and other robots who have two motors for acceleration. Very good work.

Good job! Nicely integrates ESP code and App. Extremely nice app! Only thing I had to tweak was the mapping of the direction buttons as my motors are apparently wired differently. But this is the absolute best about this whole project: It's all available on github! Great project all around! Thanks for taking the time to make the Android app available on the playstore!

Most useful and Functional app, made my day, Easy to use Code, even for me with close to 0 experience with arduino, managed to change and adjust under my needs, now it controls boat with servo and dc motors :) Great Job Thank You
