Police Siren Circuit Working Using NE555 Timer and ...
Touch Controlled Load Switch: The project is designed to develop a touch sensitive switch to control any load. A 555 timer is used in the monostable mode to drive a relay to switch ON a load for a fixed time duration.. Police Siren: This circuit is used to generate a police siren sound using two NE555 timers and a speaker. In this article, we are going to discuss on the police siren circuit ...Beep Alarm Circuit Schematic Diagram – Circuit Wiring Diagrams
This beep alarm circuit would produce beep sound. IT uses IC timer NE555 as an ON OFF clock. The first timer circuit produces oscillating frequency 1 kHz, whilst the second timer circuit is on the ON or OFF state, depending on the first circuit’s frequency. The output frequency from the first circuit affecting the ON OFF speed of the second circuit. This will result in the sound produces by ...ELECTRONIC 555(100) contact.bg
The heart of this circuit is IC No. 555. When the alert sound was working, even though the switch will continue to be the same, the sound still does not stop immediately.But it will stops automatically, when a set time period,Depending on the resistance of R3, the circuit so I set a time period equal to 1M for 1 minute 6 seconds.Robotech Maker: 555 timer ic circuit
LASER RAY Circuit This circuit produces a weird “Laser Ray” sound and flashes a white LED at approx 5Hz: LATCH Circuit This circuit is a LATCH and remains ACTIVE when the push button has been pressed for an INSTANT and released.555 Timer IC Electronic Circuits and Diagrams Electronic ...
The 555 Timer IC is one of the renowned ICs, in the electronic circles. However, its history of invention is not known to many. This article takes you on a journey of 555 timer IC from the time of its creation to the present day time.50 555 Circuits Talking Electronics
THE POWER SUPPLY Sometimes you will see a circuit as shown in the first diagram with 12v or 12v on the top rail and 0v or a negative sign or the word "negative" on the bottom rail. In this case the word negative means earth or "chassis of a car" and we commonly refer to this as "negative earth" or "negative chassis." In the second diagram, the output from a power supply has a positive 12 ...200 Best Electronics Mini Projects: Circuits, Working ...

The 555 IC is one of the simplest and most rugged IC's on the market. It has been used in thousands of applications and is extremely popular.Function Generator Definition, Working, Block Diagram,Circuit
All About Function Generators A function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine waves, triangular waves, square waves, and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.
