This is a wireless remote controlled robot using ESP8266 with L298N or L293D H-Bridge Motor Controller along with your Arduino Microcontroller, This bot is also tested in ESP8266 7, 12, 12E with or without Microcontroller. As you can see the illustration below it is demonstrated using ESP8266 Version 1 then wired with Arduino UNO Microcontroller. If your are new to ESP8266, L293D, l298N, ULN2003a, & VNH2SP30

For flashing using NodeMCU to ESP8266 01 or Flashing with ESP8266 Download Tool just follow this link & for ESP8266 Arduino Integration just follow also this link. Below you can download the binary file ai-thinker-v1.1.1.bin running at baud rate 11520. if you are using MAC OS refer to this link Note: The AT command must be end with “\r\n”. For Arduino, must type the AT command like this > Serial1.print(“AT+GMR\r\n”);

Interface

Flashing the ESP8266 01

There are two option you can follow for flashing a latest Firmware on ESP826601 using NodeMCU or ESP8266 Flash Tool for hardware you can use USB TTL UART or your Arduino Microcontroller. Note: If your using Arduino UNO you need to remote the chip.

Source Code

Open the Arduino IDE copy the code below then Goto TOOLS > BOARDS > Select Generic ESP8266 Module > Then Upload the Code Note: if your using Arduino as flasher your need to change the PIN configuration which is ESP8266 TX to ARDUINO TX | ESP8266 RX to ARDUINO RX if the flashing is done you need to change again the PIN Configuration which ESP8266 TX to ARDUINO RX | ESP8266 RX to ARDUINO TX Note the default IP address is 192.168.4.1 which can be access via web browser | http://192.168.4.1
