Other Arduino Codes and Videos by Robojax
This this video shows how to use L298N Module with ESP8266 NodeMCU or D1 Mini wami LOLIN to control speed of motor.
The link to use in the "preferences" of Arduino IDE for ESP32 board https://dl.espressif.com/dl/package_esp32_index.json Watch video for instructions.
/*
* Library Example for L298N Module to control DC motors
*
* This code is to control single motor. For two motor control, please open L298N_DC_2_Motors
* this code is ready for ESP32
* Watch video instructions for this code: https://youtu.be/2JTMqURJTwg
