What are Motors

A DC motor is like a little machine that makes things spin when you give it electricity. Imagine it as a tiny fan inside a toy car: when you connect it to a battery, the motor turns and makes the wheels move. This kind of motor is called "DC" because it runs on Direct Current, which is the type of electricity you get from batteries. DC motors are used in lots of fun projects, like robots, toy cars, and even in household appliances like fans!

Motor applications in real world

Motors are like the engines that make many everyday things move and work. Here are some fun examples of how motors are used in the real world:

1. Toy Cars and Robots:
   Tiny motors help toy cars zoom around and robots move their arms or wheels.

2. Fans:
   Motors spin the blades in fans to keep you cool on a hot day.

3. Electric Vehicles:
   Cars, buses, and bikes can use electric motors to drive without gasoline.

4. Household Appliances:
   Many kitchen gadgets like blenders, washing machines, and vacuum cleaners have motors to help them do their jobs.

5. Power Tools:
   Electric drills, saws, and other tools use motors to make work easier.

6. Drones:
   Small motors help drones fly high in the sky for fun and photography.

7. Computers and Electronics:
   Some parts of computers, like cooling fans or hard drives, use motors.

8. Helicopters and Airplanes:
   Motors (or engines) help these vehicles move through the air.

9. Conveyor Belts in Factories:
   Motors move products along belts so they can be packaged or assembled.

10. Household Curtains and Blinds:
    Motors can automatically open or close curtains, making life more convenient.

In all these examples, motors turn electrical energy into movement, helping make our lives easier and a lot more fun!How to connect Motor to Yellow tyro board

Existing Motor Code

// Check if the motor switch is pressed (reads HIGH because of the setup)
if (digitalRead(motorSwitchPin) == HIGH) {
  if (motorState == 0) {
    // Run motor in forward direction:
    // Turn on the forward motor pin and ensure the reverse pin is off.
    digitalWrite(motorForwardPin, HIGH);
    digitalWrite(motorReversePin, LOW);
    delay(2000);         // Run the motor forward for 2 seconds.
    motorState = 1;      // Change the state to indicate next press should run in reverse.
  } else {
    // Run motor in reverse direction:
    // Turn on the reverse motor pin and ensure the forward pin is off.
    digitalWrite(motorForwardPin, LOW);
    digitalWrite(motorReversePin, HIGH);
    delay(2000);         // Run the motor in reverse for 2 seconds.
    motorState = 0;      // Change the state to indicate next press should run forward.
  }
  // After running, turn off both motor control pins.
  digitalWrite(motorForwardPin, LOW);
  digitalWrite(motorReversePin, LOW);
  delay(300);            // Wait a little for the switch to be ready for another press.
}

Explanation

• What This Code Does:
  When you press the button connected to the motor (the "motor switch"), the Arduino checks which way the motor should spin. It uses a memory spot called motorState to decide:

  • If motorState is 0:
    The motor spins forward. This means the code turns on the "forward" control (turning a specific pin on) for 2 seconds.

  • If motorState is 1:
    The motor spins in reverse. The code turns on the "reverse" control for 2 seconds instead.

• How It Works:

  • The code reads the button. When the button is pressed, it looks at motorState:

    • If it's 0, the motor goes forward for 2 seconds, then motorState changes to 1.

    • If it's 1, the motor goes in reverse for 2 seconds, then motorState changes back to 0.

  • After running the motor, the code turns both controls off and waits a short time before checking the button again.

• Why It's Cool:
  This snippet lets you change the motor's direction every time you press the button, so your motor can spin one way and then switch the other way on the next press. It's like having a toy car that goes forward, then reverses when you tap it!
