As shown as below, this oscillator is a type without steady-state harmony which composed of 555, R1, R3, C1 and optics triode VT. The internal resistance is changed with the illumination, and when the light is strong, it presents in low resistivity, when the light is weak, t presents in high resistivity. So the frequency of oscillator changes with the light in the range of 1Hz～6.5kHz. So the oscillator is available to make blind man to explore the way, early dawn report Xiao etc. situation.
