Light Sensor- Arduino
This light sensor works reasonably well. Goodluckbuy list it as “Electronic Brick Light Sensor Brick Module” (SKU: 75283). That’s right brick is in there twice.
From what I could find I think made by Itead. The A-D switch lets you pick the type of output from the sensor. An analogue voltage or digital high/low. The switch point for digital is adjustable via the pot and the board uses an LM358 op-amp.
Programming and working out how to apply an analogue input value to automatically adjust an output brightness value for my series of 7-segment displays proved annoying and I had little success. I believe a lot more trial and error would be needed to make this and other displays adjust with the brightness of the room. Or perhaps I’m just a bit crap.
