TERRIFIC WITCH

The cursed TERRIFIC WITCH if you approach her, she warns you by changing her eye color and making a warning noise. Then you get a broomstick!!

All needed materials

- The first task I carried out was to think exactly what I was going to engineer.

- Once the ideas were clear, I made some realistic sketches, with measurements and to position all the accessories.

- First I started designing the code and inserted each sensor or element at each step, to verify and verify that it worked correctly and as I wanted. All this with the help of a breadboard

- Once all the elements worked as designed, I bought the materials I needed and the rest were recovered and others reused (new life).

- Thanks to making some plans at the beginning, I was able to develop the whole construction process in a logical and efficient way. However, the total time spent was around 50 hours.

- The techniques used have been a mix of: scrapbooking, carpentry, etc...

This project was a great way to me to put into practice our knowledge of Arduino and other components such as the ultrasonic distance sensor, how RGB LEDs work and being able to make an old recovered fan or buzzer work, making the final product a interaction between The Witch and the person. This practice has helped me understand the wide range of possibilities offered by Arduino to be implemented in industry or in future projects, for instance.
