The 555 timer IC is used in a variety of timer, pulse generation, and oscillator applications. It can be used to provide time delays, as oscillators, and as flip-flop elements.
The 555 timer IC is an integral part of electronics projects. Be it a simple 555 timer project involving a single 8-bit micro-controller and some peripherals or a complex one involving system on chips, 555 timer working is involved. Here, we take a look at some 555 timer circuits based on the IC. For the full list of timer-based projects check out 555 timer projects.
This variable power supply circuit can provide up to 300mA current and is variable between 6 volts to 13 volts. This project is very cheaper and easy to design.
An electronic timer is a circuit which is used to delay or switch various industrial and domestic appliances.
A boost converter is a DC to DC power converter that increases the voltage to a fixed certain level by getting a certain amount of specified input voltage. It is a class of exchanged mode power supply containing at any rate two semiconductors (a diode and a transistor) and at any rate of one energy storage component i.e a capacitor, inductor, or them both in the same combination.
The Super Sensitive Intruder Alarm circuit is designed to alert the owner when an intruder enters their home. If there is any obstacle in front of an infrared sensor, it generates an interrupt signal. This interrupt signal is given to the buzzer as output to alert the owner.
This circuit can change the tune or melody of an input audio signal with different pitch levels. The characteristics of the signal may vary at different moments in time. The melody which is produced by melody generator IC can be postponed and the pitch of the tune mottled at a different instance of time. This circuit can generate different sounds from a single melody.
This project is about PWM Motor Speed Controller using just 555 timer IC. It is useful for varying the speed of a low powered DC motor. There are many circuits on the web that can control DC motors for electronic projects purposes. But when it comes to controlling the motor uniformly and smoothly, the PWM motor speed controller is the best option like using AVR, 8051 and Arduino.
A stun gun is a device used to generate a high voltage and low current signal. It is mostly used as a weapon to stun or shock waves to the target. The shock of it gets weak or paralyses the target. For its application, some countries banned this stun gun. This is actually a weapon that can paralyze a person mentally.
Nowadays, watering crops are a normal problem in the agriculture field. It is happening because farmers have lack ideas about the availability of technologies. They lose their precious time pumping water to spread the entire field until it gets properly watered. So we here designed a automatic plant irrigation system using 555 timer ic.
A simple Ultrasonic Sound Generator that can be used for various purposes such as a sound generator, mosquito repeller, and like this. This project uses an astable mode multivibrator with IC 555 which produces the desired frequency by altering the variable resistance.
A simple led chaser circuit can be made using 555 timers and CD4017 IC with some simple steps. This circuit can be used in blinking lighting, chaser lighting, and many decorative items. By modifying the circuit with relays you can use this to control lights working on AC electric units.
I will show you how to make a darkness detector that detects darkness using the cheapest light sensor that is LDR (Light Dependent Resistor). Darkness Detector circuits can be used in applications where the light will be going to off.
I will show you how to make a simple metal detector circuit using fewer components which is a very essential device that is used for checking persons, luggage, or bags in airports/shopping malls, hotels, etc to ensure that the particular person is not carrying any metals like guns, bombs or any other metallic types of equipment.
The operation of this IR sensor is so simple when an object is in front of the sensor, led will light up. We have two IR LEDs, a transmitter and a receiver. When the current passes through the transmitter led, it will emit IR rays.
I will be going to show you a water level indicator using transistors and 555 timer IC. Water tank flow is a typical issue that prompts the wastage of water. In spite of the fact that there are numerous answers for it like ball valves which consequently stop the water stream once the tank gets full.
These days, the calling bell is basic in each house. We, everyday watch various sorts of calling bell are accessible in the market and they produce various kinds of music relying upon their usefulness. One can structure their own calling bell ringer utilizing simple electronic parts.
The 555 Timer IC is one of the most popular and most frequently used integrated circuits. It performs an array of timing tasks in the electronic circuits and there is a huge list of experiments that can be performed with 555 IC. That is why it is very popular for electronics hobbyists.
