Els alumnes han utilitzat dues plaques Micro:bit connectades a tires de LEDs Neopixel, amb un total de 30 LEDs per tira. Cada tira ha estat programada per mostrar diferents efectes i modes d\u2019il\u00b7luminaci\u00f3 que reflecteixen la seva creativitat i domini de la programaci\u00f3.<\/p>\n
Primer programa: Efectes activats per botons<\/strong><\/p>\n
En el primer programa, els alumnes han configurat la tira de LEDs amb quatre modes d\u2019il\u00b7luminaci\u00f3 diferents, activats mitjan\u00e7ant els botons i el logotip t\u00e0ctil de la Micro:bit:<\/p>\n
- \n
- Efecte Arc de Sant Mart\u00ed (Bot\u00f3 A): En aquest mode, els LEDs mostren un efecte de colors en moviment que simula l\u2019Arc de Sant Mart\u00ed.<\/li>\n
- Dos Arcs de Sant Mart\u00ed (Bot\u00f3 B): La tira de LEDs es divideix en dues seccions amb Arcs de Sant Mart\u00ed independents.<\/li>\n
- Efecte d\u2019Escombrat Groc (Botons A+B): Els LEDs s\u2019encenen seq\u00fcencialment amb color groc des del LED 0 fins al 29.<\/li>\n
- Efecte d\u2019Escombrat Blau Bidireccional (Logotip): Els LEDs s\u2019encenen en color blau des del LED 0 al 29 i tornen enrere.<\/li>\n<\/ul>\n
Segon programa: Control per so i variaci\u00f3 de colors<\/strong><\/p>\n
En el segon programa, els alumnes han creat un efecte m\u00e9s din\u00e0mic que respon al so i utilitza variacions de brillantor i color. La programaci\u00f3 es va realitzar amb les seg\u00fcents caracter\u00edstiques:<\/p>\n
- \n
- Control per so: La Micro:bit detecta sons forts (amb un llindar configurat a 180) i alterna entre dos estats: “on” (llum activada) i “off” (llum apagada).<\/li>\n
- Animacions amb canvi de brillantor i color: Quan l\u2019estat \u00e9s “on”, la tira de LEDs mostra seq\u00fc\u00e8ncies d\u2019augment i disminuci\u00f3 de brillantor per als colors vermell, taronja, verd i violeta. Cada color passa per un cicle de transici\u00f3 suau, donant un efecte visual captivador.<\/li>\n
- Rotaci\u00f3 inicial: Al comen\u00e7ament, la tira de LEDs mostra una rotaci\u00f3 del color vermell per tots els LEDs abans d\u2019iniciar les animacions de brillantor.<\/li>\n
- Apagat en estat “off”: Si l\u2019estat \u00e9s “off”, la tira de LEDs s\u2019apaga completament.<\/li>\n<\/ul>\n
Per poder alimentar les plaques de manera aut\u00f2noma s’han fet servir bateries recarregables.<\/p>\n
Aprenentatge i resultats<\/strong><\/p>\n
Amb aquests projectes, els alumnes han adquirit coneixements pr\u00e0ctics en programaci\u00f3 de dispositius electr\u00f2nics, comprensi\u00f3 de circuits i treball amb LEDs RGB. Han explorat conceptes com la detecci\u00f3 de so, la gesti\u00f3 de brillantor i els efectes de transici\u00f3, desenvolupant alhora habilitats de resoluci\u00f3 de problemes i creativitat.<\/p>\n
El resultat final ha estat una il\u00b7luminaci\u00f3 tecnol\u00f2gica i personalitzable de l\u2019arbre de Nadal, que reflecteix l\u2019esfor\u00e7 i la dedicaci\u00f3 dels alumnes. Aquest projecte no nom\u00e9s ha il\u00b7luminat l\u2019\u00c0gora, sin\u00f3 tamb\u00e9 l\u2019esperit nadalenc del nostre institut.<\/p>\n
