Mind the Keys!
Weekend project
This is a Weekend project made with Tokymaker, an intuitive way for youngs and adults to learn the fundamentals of electronics, programming and solve problems creatively. If you don’t know what is it yet, follow the link and come back later!

Problem
We have a really busy life, and we often forget to take the keys before leaving home. Then, how are we going to get back in?

Tenemos una vida muy ajetreada y a veces se nos olvída cojer las llaves al salir de casa. Entonces, ¿cómo vamos a volver a entrar?
Solution
We are going to devise a system that keeps the keys to us when entering the house and that we are advised to take them when leaving. Thanks Tokymaker!
We will use a distance sensor that detects our presence crossing the main door of the house. At that moment, with the help of a servo motor, we will extend a robotic arm with the keys, so that we can take them. We will also show on the screen a warning message: “The keys!”

Vamos a idear un sistema que nos guarde las llaves al entrar en casa y que nos avíse de cogerlas al salir. Gracias Tokymaker!
Utilizaremos un sensor de distancia que detecte nuestra presencia cruzando la puerta principal de la casa. En ese momento, con la ayuda de un servo motor, extenderemos un brazo robótico con las llaves, para que las cojamos. Además mostraremos por la pantalla un mensaje de aviso: “Las llaves!”
Material
Tokymaker
Learn to code your own prototypes using the simple visual coding interface and just one finger and program it without installing software or connecting cables. Understand the principles os electronics connecting in the most intuitive way, a large variety of sensors and actuators.
Sonar
Ultrasonic sensors are non-intrusive in that they do not require physical contact with their target, and can detect certain clear or shiny targets otherwise obscured to some vision-based sensors.

Amazing gadget! I got it as a present from a friend and I’m still amazed. It only took me about an hour to assemble, and now I’m experimenting with its possibilities. Kudos!
