En aquest apartat explicarem com fer una porta autom\u00e0tica, que s'obri sola quan s'apropa una persona. \u00c9s molt semblant a la que podem trobar als grans comer\u00e7os.<\/span><\/p>\r\n

La maqueta de la porta pot ser de moltes formes, segons la imaginaci\u00f3 de l'alumne i els consells de l'equip docent. Aqui proposem tan sols algunes idees.<\/span><\/p>\r\n

El mecanisme autom\u00e0tic t\u00e9 nom\u00e9s dos elements: sensor de dist\u00e0ncia i servomotor<\/span><\/p>\r\n

Ens caldr\u00e0 tamb\u00e9 una unitat de control, fomada per una\u00a0<\/span>targeta<\/span>\u00a0micro:bit i la placa microshield<\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/section>
