My first Raspberry Pi project is going to be a controller to tilt my Venetian blinds. I need to be able to control a number of servos and connect some sensors to measure light levels and temperature. As space is tight, I am planning to purchase a Pi Zero and the Picon Zero, so I can connect both the servos and sensors to the same hat.
What I’d like some help with is choosing suitable sensors. The Picon Zero supports ‘digital’ or analog sensors, using 3-pin GVS connectors (Ground, Volts, Signal).
Looking at the various light sensors available, the 'Adafruit Digital light / luminosity / lux sensor’ seems to be a great sensor, with good low-level range, and has an I2C interface. However I am unsure if this would be compatible with the Picon ‘digital’ input type (as the Picon Zero inputs use 3 wires and I2C seems to require four). Will it work? Is this a different type of ‘digital’ interface? Is there a more-specific name for the type of ‘digital’ input that this Picon Zero expects?
If this sensor is not suitable, can anyone recommend a suitable light sensor that would work when connected to one of the picon zero inputs?
