How to Change Motor Direction with Battery | Basics of Motor Control for Arduino & ESP32 Projects

Ever wondered how a motor runs forward and backward? In this video, we'll explore a simple but powerful concept — how the direction of a DC motor can be changed just by swapping the battery polarity. In this beginner-friendly video, we teach students the core concept of DC motor direction control using a simple battery and two wires. We first show how a bulb lights up when connected with two wires, explaining the importance of completing a circuit. Then, we connect a DC motor to a battery and show how it runs in one direction — and how changing the polarity makes it run in the opposite direction (clockwise and anticlockwise). This is the foundational concept you need to understand motor driver modules, L293D, H-Bridge logic, and microcontroller-based control using platforms like Arduino UNO and ESP32. What You’ll Learn: ✅ Why polarity matters for motors and LEDs ✅ How to make a motor run clockwise and counter-clockwise ✅ How this relates to Arduino/ESP32 motor control ✅ Basics of 0 & 1 logic to change motor direction ✅ Why motor drivers (L293D, L298N) are used in robotics #MotorDirection #DCPower #ArduinoTutorial #ESP32Projects #MotorControl #PolarityChange #ElectronicsForBeginners #DIYRobotics #STEMEducation #ArduinoProjects #LearnElectronics #RoboticsForKids #L293D #DCMotor #SimpleElectronics #EngineeringBasics #MicrocontrollerProjects #CodingForKids #DIYMotor #techforstudents #esp32 #arduino #esp32setup #esp32projects #comport #usbdriver #troubleshooting #arduinofix #esp32setup #esp32projects #techtutorial #diyelectronics #arduinoprojects #microcontroller #iotdevelopment #makers #stemeducation #coding #esp32setup #driverinstallation #aimiracle #robotics #arduino
