Light dependent resistor LDR controlled 555 timer astable mode LED flasher

Light dependent resistors (LDRs) make an astable mode 555 timer more interesting. The output continuously goes high and low (on and off) like other astable multivibrator 555 timer circuits. But, the speed in which it does so is determined by how much light is falling on the light dependent resistor.
