AM TRANSMITTER USING 555

                                   This circuit can transmit AM radio wave in MW frequency of around 600 Kilo hertz.The Timer IC 555 is used a free running multi vibrator which have been adjusted in frequency of 540 Kilo hertz.
                                 The sound signal is inputted to pin number 5 of IC from the condenser mic. And The IC converts the signal to a Amplitude modulated frequency and outputs from pin number 3 from which an Antenna of length of around 2-3 meters converts the frequency to radio waves which can be received by any Medium Wave radio receiver by tuning it to around 600 Kilo Hertz from a distance of up to 25-30 meters.
