Task-1: DC motor speed control using a microcontroller\n---\n \n\nThe aim of this experiment was to explore basic techniques for controlling DC motors and control DC motors using the L298N motor driver and the Arduino board.\n \n\n \n\nControlling DC motors using drivers and Arduino is the basic step towards implementing machine-driven complex systems with self-correcting abilities.\n \n\n \n\nSkills Learnt: DC motors’ speed and directional manipulation, Working of L298 Motor Driver, Use of Arduino board and the process of implementing code through it.\n \n\n \n\nDC motors have two parameters that can be controlled. One is speed and another one is direction. Speed can be controlled by Pulse Width Modulation (PWD) and direction of rotation can be controlled by H-bridge which are embedded in the L298 Driver. These parameters can be physically manipulated by connecting a Potentiometer and Push Button through an Arduino board. The circuit is connected as shown in the figure.\n\n\n \nAfter connecting, the code is uploaded to the Arduino through Arduino IDE from a computer. Now the speed can be controlled by the potentiometer and the direction through Push Button.\n \n\n\n<iframe height="\315"">\n\n \n\n \n\n\n\n---\n---\n---\n---\n---\n---\n---\n---\n---\n---\n---\n \n\n---\n---\n---\n\n\n\n# Task-2: LED Toggle Using ESP32\n---\n \n\n \n\nThe aim of this task was to create a standalone web server with an ESP32 that controls the LED connected with ESP32 GPIOs using the Arduino IDE.\n \n\n \n\n Skills learnt: Basic working and application of ESP32 and Arduino IDE.\n \n\n \n\n\n This was a simple experiment which gave an insight into IOT.
