En aquest apartat explicarem com fer un<\/span>\u00a0sistema de reg\u00a0<\/span>autom\u00e0tic<\/span>, que ens regui una planta quan la terra estigui seca.<\/span><\/p>\r\n

El sistema de reg<\/span>\u00a0pot 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\u00a0<\/span>humitat<\/span>\u00a0i 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>
