Arduino:
“The Arduino Diecimila is a microcontroller board based on the ATmega168 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; [...]
Código para o Arduino que permite ler as variáveis de três sensores bend instalados numa luva, utilizando um circuito com Multiplex que faz utilizar uma só porta analogIn do Arduino.
