The example demonstrates how to use an ultrasonic sensor with Quarky.

Connections

Now we will connect the Ultrasonic Sensor to the Robot. The sensor and the robot have the following pins:

  1. Ultrasonic Sensor Pins:
    1.  VCC
    2. GND
    3. Trig
    4. Echo
  2. Quarky Pins:
    1. GND
    2. V
    3. D1
    4. D2

We will start with connecting the ultrasonic sensor with Quarky using the 4 set wire provided in the kit. But, first, make the connection in the following way:

  • First, connect the VCC of the ultrasonic sensor with the V pin on the Quarky.
  • Connect the GND of the ultrasonic sensor with the Ground pin on the Quarky.
  • Connect Trig of the ultrasonic sensor with D1 pin on the Quarky.
  • Finally, connect the Echo of the ultrasonic sensor with the D2 pin on the Quarky.

The example demonstrates how to make a sprite be fixed to a point but can rotate. The wand is hanging like a pendulum.

The center of the wand in the costume is the point of rotation.

In this example, you understand the effect of the density, roughness, and bounce properties of the sprites. The ball falls from the top randomly, and the bell is fixed but can rotate. 

In this example, you understand the effect of the density, roughness, and bounce properties of the sprites. The ball falls from the top randomly, and the bell is fixed but can rotate.

Script of Bell

The bell center is changed to make it swing from the top.

Script for Ball

This script creates clones of the ball every 0.5 seconds.

This script assigns the properties of the clone.

Output

We will change the density of the bell and the ball in the block – set sprite density () roughness () bounce (). This will result in different simulations.

  1. Bell is very light and the balls are very heavy: The inertia of the balls will affect the bell too much.
  2. Bell is very light and balls are also very light: The bell is less affected by the ball. Gradually the bell slows down.
  3. Bell is very heavy and the balls are very light: The bell is not affected at all. The balls are thrown without adding any effect on the bell.
  4. Bell is very heavy and the balls are also very heavy: Same as option 2 – The bell is less affected by the ball. Gradually the bell slows down.
