Frequently Asked Questions (FAQ)

  • Q: How do I connect an NE555 and a CD4017?

    A: You can build simple LED chaser circuits using CD4017 and NE555 timer. There are hundreds of projects in the internet for making such simple LED chaser circuits. more

  • Q: How do I get started with an NE555 timer?

    A: The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package. more

  • Q: How do I create a PWM signal with an NE555?

    A: PWM is a technique used everywhere within electronics to vary the power supplied to devices and components such as motors, LED's and fans.Controlling the ratio a component is high (on) to the time its low (off) can vary the overall power supplied to it. For example if a motor was powered from a 12v power supply and 50% of the time the power supplied was low and 50% was high then the average voltage the motor receives is 6v making it run half as fast. more

  • Q: Where can I find an NE555 circuit?

    A: The 555 timer is a simple integrated circuit that can be used to make many different electronic circuits. With this information you will learn how how the 555 works and will have the experience to build some of the circuits below. more

  • Q: Where can I find an NE555 pinout diagram?

    A: When drawing a circuit diagram, always draw the 555 as a building block, as shown below with the pins in the following locations. This will help you instantly recognise the function of each pin: more

  • Q: How do I use the NE555 online calculator?

    A: The 555 timer shown above is configured as an astable circuit. This means that the output voltage is a periodic pulse that alternates between the VCC value and 0 volts.The frequency is the number of pulses per second. The formula to calculate the frequency of the output voltage is: more

  • Q: How do I connect an NE555 in astable circuit?

    A: The 555 timer is capable of being used in astable and monostable circuits. In an astable circuit, the output voltage alternates between VCC and 0 volts on a continual basis.By selecting values for R1, R2 and C we can determine the period/frequency and the duty cycle. The period is the length of time it takes for the on/off cyle to repeat itself, whilst the duty cycle is the percentage of time the output is on. ie. T1/T. In this type of circuit, the duty cycle can never be 50% or lower. more

  • Q: How do I connect an NE555 in monostable circuit?

    A: This calculator computes for the output pulse width of a 555 timer monostable circuit.The 555 timer above is configured as a monostable circuit. This means that the output voltage becomes high for a set duration (T) when a falling edge is detected on pin 2 (trigger). The circuit above is also called a one-shot circuit. This calculator is designed to compute for the output pulse width of a 555 timer monostable circuit. more

  • Q: Where can I find various NE555 timer circuits?

    A: We have seen that Multivibrators and CMOS Oscillators can be easily constructed from discrete components to produce relaxation oscillators for generating basic square wave output waveforms. But there are also dedicated IC’s especially designed to accurately produce the required output waveform with the addition of just a few extra timing components. more

  • Q: How do I make a delay timer with NE555?

    A: In this project we are going to design a Simple Time Delay Circuit Using 555 Timer IC. This circuit consists of 2 switches one for start the delay time and other for reset. It also has a potentiometer to adjust the time delay, where you can increase of decrease the time delay by just rotating the potentiometer. more

  • Q: How do I make a NE555 pulse generator?

    A: This is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator with a 50% pulse duty cycle. The difference from the standard design of a 555 timer is the resistance between pins 6 and 7 of the IC composed of P1, P2, R2, D1 and D2. more

  • Q: How do I use an NE555 as an oscillator?

    A: The 555 Timer IC can be connected either in its Monostable mode thereby producing a precision timer of a fixed time duration, or in its Bistable mode to produce a flip-flop type switching action. more

  • Q: How do I connect NE555 and Arduino?

    A: The NE555 Timer, a mixed circuit composed of analog and digital circuits, integrates analog and logical functions into an independent IC, thus tremendously expanding the applications of analog integrated circuits. It is widely used in various timers, pulse generators, and oscillators. In this experiment, the SunFounder Uno board is used to test the frequencies of square waves generated by the 555 oscillating circuit and show them on Serial Monitor. more

  • Q: Where can I find an NE555 bistable circuit?

    A: The 555 timer IC can be used with a few simple components to build a bistable circuit, also known as a 'flip-flop'. It is a very simple memory circuit. The circuit is called a bistable because it is stable in two states: output high and output low. more
