In France and some other countries playing the flute is included in music lessons at school. This project is to share a possible solution for children or music lovers with limb differences and agenesis to play the flute.

Basic Idea: Use an Arduino board to make a circuit that if a button is pressed then the corresponding servo motor will rotate to cover the hole on the flute with the help of little sticks which serve as fingers.

Step 1 Arduino programming

If you made mistakes with the wiring or the motors placements, don’t worry you can still change the code. For example, if you’re button 1 is controlling the first motor but you want it the control the fourth motor for placements purposes, you can go in the if the loop of the concerned button, here button 1 (if statut1==...), and change the number of the servo motor.

Step 2 Soldering the circuit

(1) prepare all the material :

An arduino sheild
Soldering materials
4 servo motors
4 buttons
120cm wires * 12
60cm wires * 8

(2) Braid the wires

This step is for better wiring management and for avoiding short circuits.

Braid the 60cm wires as 2 wires in each group. And 4 groups in total. It will be easier for later soldering if you use different colors within each group. We use black wires for representing GND, red for 5V entry, And green ones representing signals.

Braid the 120cm wires as 3 wires in each group. And 4 groups in total. Same with above, It will be easier for later soldering if you use different colors within each group.

(3) Soldering wires to buttons and motors

3.1 Soldering the 2 wires braid to the button. 4 braids for 4 buttons.

Please always connect the teeth on the same side to the wires ( as the red lines)

3.2 Soldering the 3 wires braid to the motor. 4 braids for 4 motors.

Cut the plastic end of the motors and solder the 3 wires with the braid. It would be easier for later soldering if you separate the color of wire for GND, 5V, and signal.
