Denna modul har ett MPR121-chip som \u00e4r en komplett l\u00f6sning f\u00f6r kapacitativa touch-knappar. Chippet har ett I\u00b2C-interface f\u00f6r smidig kommunikation till en mikrokontroller. Modulen kan hantera upp till 12 elektroder. \u00c5tta av anslutningarna kan dessutom anv\u00e4ndas som generella I\/O-anslutningar, eller f\u00f6r att driva lysdioder ist\u00e4llet.\u00a0I\u00b2C-adressen \u00e4r satt till 0x5A, men g\u00e5r att st\u00e4lla om genom att sk\u00e4ra av en ledning p\u00e5 baksidan som ansluter ADD till jord och sedan koppla ADD till Vcc, SDA eller SCL f\u00f6r att s\u00e4tta adressen till 0x5B, 0x5C eller 0x5D respektive.<\/p>\n

T\u00e4nk p\u00e5 att modulen drivs med 3,3V och om du vill koppla den till ett standard 5V-Arduino-kort eller liknande m\u00e5ste du anv\u00e4nda en logikniv\u00e5omvandlare<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
