PCBA Design - Light Switch Sensor

Easy design This is for a chicken shed light. As chickens are in shed they need to have lighting. Will need a design of electronics of layout, components, and how each component works plus the reasoning behind each one. This will compromise of a 12V DC power A LED strip connected to a photodiode sensor. Will the design to be able to control the brightness of the LED, and the sensitivity of the Photodiode sensor. The LED will need to light, when the photodiode/LDR detects light, and turns off when the sensor sees no light. Normally LDRs are used to turn on light when it is dark. But for this will need it to turn on light when sensor detects light! The LED light is in the chicken shed, and the light sensor will be outside the shed. Summary: + will need sensor to be adjustable maybe via pot switch + LED light brightness to be adjustable Very easy simple project!
