I'm completely new to Arduino and I could use some help with my project. I recently purchased an Arduino Uno board and I'm trying to build a small car that can be controlled remotely via WiFi. I'm planning to use the L298N motor driver for controlling two DC motors and an ESP8266 ESP-01 module for WiFi connectivity.
Here's what I have:
Arduino Uno board
L298N motor driver
ESP8266 ESP-01 module
Two DC motors for the car
I've done some research and I understand the basics of how the L298N motor driver works, but I'm not sure about the wiring and coding specifics for my project. I'm also not familiar with how to integrate the ESP8266 module with the Arduino code.
Could someone please help me with the following:
How to wire the Arduino Uno, L298N motor driver, and DC motors properly?
Provide a basic code example to control the motors with the L298N driver.
How can I integrate the ESP8266 module to control the car via WiFi?
I would greatly appreciate any guidance or suggestions you can provide. Thank you so much for your help!
Welcome! This is not a project for a beginner. I highly recommend you get a copy of the Arduino Cookbook and read it cover to cover, and do each of the projects that utilize one of the parts you have purchased. If you do not have the time we have a for hire section.
It is an interesting project but we are not a free code writing service. We will help out with your
code but first you have to make an attempt to write it, post it and explain what is not working
properly. If there is hardware it is always best to post links to technical information as there are
many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post an annotated schematic (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here.
Thanks for getting back to me. Well, when it comes to coding, I'm not too shabby. My question is more about wiring, though. The real aim of my post was to see how your community would react to a newbie. I guess I'm not really feeling this forum anymore.
For my request for help, I managed to achieve what I wanted. Then, I improved it by removing one motor and replacing it with a servo motor to control the direction. I kept the second 6V motor for moving forward and backward, and used the ESP01 to control the car via the internet. I created a hotspot on my phone for the WiFi module to connect to, allowing me to control everything via the internet, not just locally. All this just to say that it's not as complicated as it seems.
