WeDo 2.0 Mini Piano

This robotic construction uses both the tilt sensor and the distance sensor to produce piano sounds. The idea behind it is as follows: when the human finger presses down the upper hinged level (which later returns to the level position with the help of the two red rubber bands, not shown here as they are suspended at the back), the tilt sensor which is located just under the upper level, changes value from 0 to 2. This change of value triggers in turn the measurement of the distance sensor from the now lowered human finger, and with the help of a simple mathematical formula based on this value, it finally produces the sound of a piano note.

Εξαιρετικό!!!

Δυστυχώς, Μαρία, στο KZbin κανάλι μου δεν δημοσιεύω οδηγίες κατασκευής σε ό,τι παρουσιάζω - μόνο τον προγραμματισμό. Τα videos εδώ δημοσιεύονται για εκπαιδευτικούς σκοπούς και για αφορμή έμπνευσης & δημιουργίας από τη μεριά του θεατή. Λυπάμαι... Unfortunately, Maria, in my YouTybe channel I do not publish construction instructions for everything shown - just the programming. All videos found in here are only for educational purposes and for inspiring creativity to viewers. I am sorry...

Interesting. I like your idea of combining two sensors for detecting six piano keys. And I like it that the Scratch code stays understandable for kids. Nice job!
