Interface LDR Sensor With ARM7

Description A Light Dependent Resistor(LDR) or a photoresistor is a non-linear device whose resistivity is a function of the incident electromagnetic radiation. A light-dependent resistor works on the principle of photoconductivity. Photoconductivity is an optical phenomenon in which the conductivity of the material (Hence resistivity) reduces when light is absorbed by the material. When light … Continue reading Interface LDR Sensor With ARM7
