  Serial Communication between arduino and bluetooth module Introduction In the world of embedded systems and IoT (Internet of Things), wireless communication is a cornerstone. Among the various wireless communication protocols, Bluetooth stands out due to its simplicity, low power consumption, and ease of use. This blog explores the integration of Bluetooth modules with Arduino, focusing on serial communication—a fundamental aspect for enabling Arduino to communicate wirelessly with other devices. Understanding Serial Communication Serial communication is a method of transmitting data one bit at a time, sequentially, over a communication channel or computer bus. It is one of the most common forms of communication between computers and peripherals. Key Concepts of Serial Communication Baud Rate: The speed of data transmission, measured in bits per second (bps). Common baud rates include 9600, 19200, 38400, 57600, and 115200. TX and RX: TX (transmit) and RX (receive) are the pins used f

  Building a Bluetooth Controlled Car with Arduino In this blog, we’ll walk through creating a Bluetooth-controlled car using an Arduino and a Bluetooth module. This project is a great way to delve into the world of robotics, combining mechanical control with wireless communication. By the end of this tutorial, you'll have a basic understanding of how to control a car using your smartphone via Bluetooth. Introduction Controlling devices wirelessly is not only convenient but also opens up a myriad of possibilities in robotics and IoT projects. By integrating Bluetooth into an Arduino-powered car, we can create a simple yet powerful system to navigate and control a car remotely. We will cover the necessary hardware, software setup, and code implementation to get your Bluetooth-controlled car up and running. Required Components Arduino Uno (or any other compatible board) HC-05 Bluetooth module Motor driver module (L298N or similar) DC motors with wheels (2 or 4 depending on your desig
