TinkerKit LDR jutiklis

TinkerKit LDR (Light Dependant Resistor) jutiklis.

Aprašymas:

Šis modulis yra 12mm mygtukas, standartinė TinkerKit 3 kištukų jungtis. Žalios šviesos LED signalas įsijungia, kai modulis yra tinkamai maitinamas ir geltonas šviesos LED užsidega, kai jutiklis pajungiamas.

Kodo pavyzdys:

/*
  Analog input, analog output, serial output

 Reads an analog input pin, and T000090 LDR Analog Sensor connected to I0, maps the result to a range from 0 to 255
 and uses the result to set the pulsewidth modulation (PWM) on a T010111 LED Module connected on O0.
 Also prints the results to the serial monitor.
