DIY WIFI RC Car With ESP8266 and Arduino IDE
Intro: DIY WIFI RC Car With ESP8266 and Arduino IDE
This project is an example of remotely controlled car via WIFI. The circuit is based on ESP8266, and the software is written in the Arduino IDE. As an engine driver, I used the L298N. The vehicle's speed is controlled by PWM in the range of 0 to 1023. Digital control offers more possibilities than the usual controller. I also added a RGB LED as light and buzzer as a horn.

STEP 3: Software for ESP8266
Before you upload the software to ESP8266 setup your WiFi connection.
#define WIFI_SSID "" #define WIFI_PASSWORD ""
#include <ESP8266WiFi.h> #include <WiFiClient.h> #include <WiFiUdp.h> #include <ESP8266WebServer.h> #include <ESP8266mDNS.h> #include <Adafruit_NeoPixel.h> #define PIN D8 #define LICZBADIOD 1 Adafruit_NeoPixel pixels = Adafruit_NeoPixel(LICZBADIOD, PIN, NEO_GRB + NEO_KHZ800); //--------------------------------------- #define CMD_NONE 0 #define CMD_LED 1 typedef struct TRCcar{ short speed; short turn; uint8_t flags; uint8_t cmd; uint8_t r; uint8_t g; uint8_t b; }; //--------------------------------------- //const char COMPILED[] PROGMEM = { __DATE__ " " __TIME__ }; #define WIFI_SSID "" #define WIFI_PASS "" int cnt_loop = 0; long time_loop; //--------------------------------------- void setup() { Serial.begin(115200); Serial.println( "\r\n\r\n--------------------------------------" ); Serial.println( "START setup" ); delay(500); BlinkLedSteup(); MotroSetupA(); MotroSetupB(); //--------------------------------- WiFi.mode(WIFI_STA); //WiFi.mode(WIFI_AP_STA); //Serial.print("Setting soft-AP ... "); //Serial.println(WiFi.softAP(GetNameDev().c_str(), "1234") ? "Ready" : "Failed!"); //Serial.println(WiFi.softAP("ESP8266-test", "1234") ? "Ready" : "Failed!"); WiFi.begin(WIFI_SSID, WIFI_PASS); //WiFi.hostname( GetNameDev() ); Serial.print("Connecting to WIFI"); // Wait for connection while( WiFi.status() != WL_CONNECTED ) { delay(500); Serial.print("."); } Serial.println(""); Serial.print("Connected to "); Serial.println( WIFI_SSID ); Serial.print("IP address: "); Serial.println(WiFi.localIP()); //--------------------------------- UDPSetup(); BeepSetup(); pixels.begin(); //pixels.setPixelColor(0, 255, 0, 0); //pixels.show(); Serial.println( "END setup" ); } void loop() { time_loop = millis(); BlinkLed(); SerialEvent(); SerialCMD(); UDPLoop(); BeepLoop(); }Download source code
STEP 4: Computer Control Software
The program I control wrote in C #. For PC communication with ESP8266 I used UDP protocol. All commands are executed immediately without delay. The car is driving great, I think much better than the original controller.

thanks man
i just started with nodemcu and so far only your codes seems to work
I am not good at programming
i need help to control it from android device using roboremo app
