Car locator device

This car tracking device circuit can be used to locate car in a parking or other objects and is made up of two parts. The first part of this car tracking device circuit is an RF oscillator based on Lm555 timer and the second part is a sensitive receiver .
To find the object using this car tracking device circuit is use a visual indications with 5 LEDs which indicate the signal strength.
Tank circuit C2 and L1 is used to tune the transmitter. The antenna is coupled to the transmitter through C3 and must be a telescopic antenna or a length of hookup wire . At the receiver, the incoming signal is tuned by C4 and L2 before being passed on to the 741 IC.
After build , the car tracking device ( receiver and transmitter ) will need to be tuned. We need to tune the transmitter until all of the receiver's LEDs light and adjust Rv2 until you get a maximum strength reading only when the receiver's antenna is pointed directly at the transmitter.
