Create a circuit which indicates 3 levels of ambient light intensity using 2 LEDs as indicators:

Good light Both LEDs ON

Medium light One LED ON

Poor light Both LEDs flashing at about 2 Hz

Such a circuit might be useful to guide people in an office about how much lighting is needed to ensure minimum eye strain while doing certain things such as detailed drawing (good light), general office work (medium light) or socializing (poor light).

The components are below.

1k good light 150k-180k poor light 10-20k med light.

Light Detector Circuit Writeup

In this project, I designed a circuit using specified components to detect light intensity using a light-dependent resistor (LDR).
The circuit is powered by a 5V battery.
The LDR is used in series with a 10k resistor to generate a voltage. This voltage is used throughout the circuit to achieve the required behavior...
