Diseñado para facilitar la entrada y la funcionalidad del usuario
Detección de presión a través de los 7 pines de salida
El Teclado Numérico de 12 Botones SparkFun es un teclado básico de 12 botones que ha sido diseñado para facilitar la entrada y la funcionalidad del usuario. Los botones están configurados en un formato de matriz. Esto permite que un microcontrolador 'escanee' los 7 pines de salida para ver cuál de los 12 botones se está presionando.
Cada uno de los 12 botones del teclado ha sido etiquetado 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, * y # y ha sido formateado en el mismo diseño que el teclado de un teléfono con cada resistencia de pulsación oscila entre 10 y 150 ohmios.
ADVERTENCIA: Este producto puede exponerlo a sustancias químicas, incluyendo plomo y compuestos de plomo, que el Estado de California reconoce como causantes de cáncer y defectos de nacimiento u otros daños reproductivos. Para obtener más información, visite: www.P65Warnings.ca.gov.
