3.1.13 Expendedor de papel

Toilet paper disposal

Este es un sencillo proyecto realizado con Lego Spike Prime usando un sensor de distancia o sensor ultrasónico. Tambien se ha incluido un botón (sensor de presión) para recuperar papel en caso de que salga más papel de lo debido.

Hemos usado papel higienico al ser mas manejable que las toallitas de papel y estar disponible en todos los colegios.

Para que funcione, solo hay que pasar la mano por delante del sensor de distancia y sale una cantidad exacta de papel.

Me inspiré en los expendedores secamanos de los aeropuertos. Espero que os guste.

This is a simple project made with Lego Spike Prime using a distance sensor or ultrasonic sensor. A button (pressure sensor) has also been included to recover paper in case more paper than necessary comes out.

We used toilet paper because of its smaler size and availability at schools.

To make it work, you just have to pass your hand in front of the distance sensor and an exact amount of paper comes out.

I was inspired by the hand-drying machines at airports. I hope you like it.
