Light Intensity Measurement using AVR microcontroller

Introduction In this project interfacing of LDR with ATMEGA8 microcontroller is done. In ATMEGA8 10 bit ADC feature is used to measure the intensity of light. An LDR is a transducer which changes its resistance when light is incident on the surface. LDR works on the principle of photoconductivity. Now the principle says that when …
