In this Blog i am going to teach you how to control speed and direction of dc motor using nodemcu WiFi module and l293d motor driver. Nodemcu will serve a web page on your mobile, desktop, laptop or notebook web browser. Web page enlists the dc motor controls. User can control the rotation speed of motor from web page and change the dc motor rotation direction through web page controls. The tutorial also teaches about how to interface h bridge l293d ic with nodemcu esp8266 12e WiFi module.     

The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously .This Motor Driver is designed and developed based on L293D IC.

L293D is a 16 Pin Motor Driver IC. This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V.


  • NodeMCU
  • Dual H-Bridge L293D Motor Driver board
  • DC Motors
  • Bread board
  • Connecting Wires (Optional)
  • Jumper Wires
  • Batteries
  • Battery Clip
  • Micro USB Cable


It is a dual H-bridge motor driver IC, that can drive two motor simultaneously. One H-bridge is capable to drive a DC motor in bidirectional. L293D IC is a current enhancing IC as the output from the sensor or micro controller is not able to drive motors itself so L293D is used for this purpose.

Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-bidirectionally, or one bi-polar or uni-polar stepper motor. Just make sure they’re good for under 600mA since that’s the limit of this driver IC.


  • Wi-Fi Module – ESP-12E module similar to ESP-12 module but with 6 extra GPIOs.
  • USB – micro USB port for power, programming and debugging
  • Headers – 2x 2.54mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins
  • Misc – Reset and Flash buttons
  • Power – 5V via micro USB port
  • Dimensions – 49 x 24.5 x 13mm
