The Light D1 sensor is a digital light sensor module, which can detect the light intensity.

Introduction of the Sensor Pin

Light D1 Sensor
General Pin Out Sensor / Trinket's Pin Out
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
