Components Needed Arduino Board : Options like Arduino Uno or Nano. Sensors : Ultrasonic sensor for obstacle detection. IR sensors for line following (if needed). Motors : DC motors or servo motors for movement. Motor driver (like L298N) to control motors. Chassis : A robot chassis to hold the components. Power Supply : Batteries or a power bank. Additional Electronics : Jumper wires and a breadboard. LEDs for indicators (optional). Camera Module : For capturing images of text. Wi-Fi Module (ESP8266) : For sending data online. SD Card Module : If you want to store data locally. Steps to Build the Article Robot Design the Chassis : Assemble the motor mounts and wheels on a suitable base. Attach the Arduino board, battery, and modules securely. Set Up the Motors : Connect motors to the motor driver and establish a connection to the Arduino. Program basic motor movements (forward, backward, turn). Incorporate Sensors : Attach the ultrasonic sens...

  Creating a water pump system using Arduino can be an exciting project, integrating electronics with practical applications. In this guide, we'll discuss the necessary components, design, and coding to build your own Arduino-controlled water pump. Components Needed Arduino Board : Any model (e.g., Arduino Uno) Water Pump : A small DC pump or submersible pump Relay Module : To control the pump with high voltage Power Supply : Suitable for the pump (e.g., 12V battery or adapter) Water Tubing : To connect the pump to your water source Breadboard and Jumper Wires : For connections Optional Sensors : Such as a moisture sensor, float switch, or flow meter Circuit Diagram To create your circuit: Connect the water pump to the relay module. Connect the relay module to a power source. Connect the control pin of the relay module to one of the digital pins on the Arduino. (Optional) Connect any sensors to read moisture levels or water presence. Basic Code Example Here’s a simple ...
