Given Below is the circuit of "Light sensitive Motorbike".
Here are the components you require to make this Electronic Kit:
Parts List:
one IC 555 timer
one 27k resistor
one Light dependent resistor(LDR)
one non-electrolytic 0.01 Micro farad/ 10 nano farad capacitor
one electrolytic 1 Micro farad capacitor
one electrolytic 10 Micro farad capacitor
one speaker (8 ohms/0.25 watt)
and ofcourse 6V power source.
What does this circuit do?
The IC oscillates producing a motorbike/motorboating sound depending on the light falling on the LDR by waving your hand over it, you can have the effect of a motorbike approaching and fading away.
