TinkerKit sukamas potenciometras

TinkerKit sukamas potenciometras.

Šis modulis yra jutiklis. Yra OUTPUT jungtis, kuri turi būti prijungta prie vieno iš įvesties jungčių esančios ant TinkerKit plokštės. Potenciometras yra dažniausiai naudojamas kintamasis rezistorius. Sukant rankenėlę, galite keisti išėjimo įtampą tarp 0 ir 5V. 

Kodo pavyzdys:

/*
  Analog input, analog output, serial output

 Reads an analog input pin, and T000140 Rotary Potetiometer 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.
