Hello and welcome to the last part of our Disco Glasses series.
In today's part we will summarize all relevant information for the construction of the glasses, show some pictures of the animation sequences and of course give our glasses a functional upgrade again. The function upgrade consists of a vibration sensor, activated by your dancing movements in the disco, to give our Micro Controller information about your "dance behaviour" on the dance floor. The light sequences of the glasses are controlled from this information.
In other words, your glasses respond to your rhythmic dance moves! Well, how does it all work technically?
As a core element, we first need a vibration sensor. This is available in the shop in several versions. Each of these sensors reacts slightly differently to movements. So the end result will of course also depend on the sensor used. I recommend that KY-002n Sensor Module to be used as a vibration sensor. I also have this in my own experimental constructiontand used in developing the code. It is important that the sensor is activated by mass. This means that in the event of a "shock", the sensor used closes the contact after GND for a short time.
Type: If necessary, try different sensors of your own to get your best result. A selection of alternative sensors can be found at the end of this blog!
The second new hardware component requires an even simpler switch. This switch is used to switch between the old self-contained mode known from Part 2 on the new mode reacting to the movements. Switching between modes can be done at any time. For example, during an ongoing programme!
Now we come to the wiring of the two new components in our glasses.
As can be seen on the switchboard, the vibration sensor sits between GND and Port 10 and the switch between GND and Port 11 of the processor. The wiring of the button has not changed:
Also the wiring of the two WS2812 rings has not changed compared to the previous part of the series:

Durch kurzen Druck auf den Taster können die Animationen nun auch wieder nacheinander aufgerufen werden. Neu ist, das jetzt durch einfaches betätigen des Schalters zwischen den Funktionsmodi „Standalone“ und „Feedback“ umgeschaltet werden kann.
Es reagiert dabei jede! der insgesamt vier Animationen leicht unterschiedlich auf den Vibrationssensor, falls der Modus „Feedback“ gewählt wurde.
Als kleine Vorstellungshilfe habe ich einmal alle 4 unterschiedlichen Animationen fotografiert:
Starshower:
Rainbow:
Motion of two colors:
Halloween:
Bitte beachtet, das in beiden! Modi die Animationen nicht sofort auf die nächste Animation umschalten, sondern immer erst die aktuelle Sequenz beenden, bevor die nächste Animation gestartet wird.
Ich wünsche nun viel Spaß beim Nachbauen der Discobrille. Vielleicht möchtest du ja weitere Animationssequenzen dazu programmieren, falls dir die 4 vorhandenen nicht ausreichen sollten?
Probiere auch mal andere Sensoren aus, wie zb:
Oder Ihr versucht es mit einem Sensor aus den verschiedenen
