Buzzer Circuit With 555 Timer. This 7555 timer is operated in astable mode to continuously and produces the waveform. This is a low power ic of 555 series.
Thus the tv signals were jammed. On pressing the set button the trigger pin 2 goes low vcc 3 making the output of lower comparator inside 555 to go high for an instant. This circuit produces a continuous signals that confuses the tv remote.
Initially trigger pin 2 and reset pin 4 are pulled up using resistors r1 and r2.
In this red led s are flashed for three times and blue led s are flashed for. This circuit produces a continuous signals that confuses the tv remote. This is a low power ic of 555 series. But now we like to use the ic 555 timer more than.
