Two sets of led’s were used for indicating left and right signal. Bike Turning Signal Circuit: Here is the circuit showing bike turning signal.555 timer plays a main role in this circuit.In this red LED’s are flashed for three times and blue Led’s are flashed for three times alternately. Police Lights using 555 Timer: The circuit shown here simulates the police car lights.Ding Dong Sound Generator Circuit: Here is the circuit for producing Ding Dong sound.This circuit produces a continuous signals that confuses the TV remote. TV Remote Jammer Circuit: Here this circuit shows a TV remote jammer circuit using 555 timer IC.The simple circuit shown here will produce an alarm when any intruder is detected. Super sensitive intruder Alarm: This circuit shows an intruder alarm using 555 timer.This circuit turns of the supply and produces and alarm as an indication. When there is any abnormal voltage (either high or low). High and Low Voltage Cutoff with Delay and Alarm: The circuit shown here gives protection to the electrical equipment.Go through the article for more information. Thus the number of pulses generated in one sec can be measured using logic. Timer in mono stable mode is used a timing signal. The timer in astable mode generates the pulses and these are fed to a counter. One in astable mode and another one in mono stable mode. The two 555 timers are operated in two modes. Frequency Counter Circuit: This project shows a frequency measuring circuit.This circuit is designed using 555 timer IC. LC Meter Circuit using 555 Timer: The LC meter circuit shown here will measure the value of a reactive element like capacitor or an inductor.Audio signals are frequency modulated and video signals are PAL modulated. This circuit amplifies and transmits the signals. TV Transmitter Circuit:The TV Transmitter circuit designed here can transmit audio and video signals.The circuit shown here is build using a 555 timer circuit. Because of its ear piercing and irritating sound it can get immediate attention. Screaming Siren Circuit: Screaming Siren can be used as an Alert signal.It compares the input voltage with the two reference voltages and produces an equivalent voltage at the output. Schmitt trigger is a regenerative comparator. 555 Timer as Schmitt Trigger: Here the 555 timer is used as a Schmitt trigger.How 555 Timer IC Testing Circuit Works?: This article explains the working of a 555 timer IC tester.This article explains the working of this mode. Monostable Multi vibrator using 555 Timer: In monostable mode 555 timer changes its state when only external trigger is applied.This article explains the working of timer in this mode. Astable Multivibrator Using 555 Timer: Astable mode is also called free running oscillator.IN this state 555 timer can trigger between two states without applying between any external triggering.Different modes ,pin configuration, applications of the timer are also explained. ![]()
