About this project

Introduction

Today I have found a mini DC motor with a small solar shield in the drawer and tried the same: a useful case for Christmas seems to me to be the gifts presentation.

Cardboard platform

Therefore, some corrugated cardboard of a large online mail-order company cut into a round shape with scissors and glued together with paper glue a second corrugated cardboard for reinforcement. On one side white with spray paint dyed and already the presented ring is presented upgraded with bows.

Such superstructures are often seen in telephone- or jewelry stores that want to put your goods in perspective. Here also for you the possibility to represent your goods at (online) auction houses accordingly.

Attach Propeller

The corrugated cardboard is attached to a small propeller, which is connected to the 2mm shaft of the engine, centered as possible so that the construction does not start to eggs but gives a nice round run.

Connect Arduino

Now connect the Arduino with GND and Pin 3 to the motor and our re-use is done.

final presentation

Via the Serial Monitor is now expected to input at least "50" to provide the initial power for startup of the rotation. Once the rotation has settled, you can reduce it to "25" if you wish a slower rotation. In the video, a transparent glass bowl has been used. This is optional and was used to complain about the structure.

Since the engine is delivered with a solar shield, a low-priced operation during the summer behind a shop window is quite conceivable.

With this I greet all lovers and lovers, who assure their mutual connection with a beautiful ring and wish a little peace and reflection with regard to the birth of Jesus (Bible, Matthew 1, 18ff).

At my age I settle for some sweets:

  pinMode(motorPin, OUTPUT);
  Serial.begin(9600);
  while (! Serial);
  Serial.println("Speed 0 to 255");
  Serial.println("But the advice 50 to 255. Because the minimum voltage required to start the motor is 50.");
}

  if (Serial.available())
  {
    int speed = Serial.parseInt();
    if (speed >= 0 && speed <= 255)
    {
      analogWrite(motorPin, speed);
    }
    delay(4000);
  }
}
