Figure 13: Placing Oscilloscope Figure 14: Simulation using oscilloscope How to perform simulation on NI Multisim Place the oscilloscope on the schematic capture, connect the output of 555 timer to the channel A terminal of oscilloscope and negative terminal of channel A to ground. Click on simulate–>Instruments and select oscilloscope. To measure the frequency from the output pin of the 555 timer, connect this to the oscilloscope. Place the GND on the schematic capture, drag the wire from the GND pin to the ground terminal. In group drag down, select group as sources–>Power sources and in component section ground. The ground terminal and the oscilloscope must be placed in the schematic capture to measure the frequency.Ĭlick on place, select components, select a component pop-up appears. The other end of R3 is connected to the C2 and then to the control voltage pin of the 555 timer.

Next, we must place the power source, resistors, capacitors, and variable resistors. Figure 4: Selecting Ideal 555 timerĭrop the 555 timer on the schematic capture window. Search result pop-up box appears, select 555_virtual and click ok. In component section type 555, click on search. The design requires 555 IC for this design, click on search, a component search pop-up appears. Start placing the components, click on place, then select components, we will get select a component pop-up. NI Multisim tutorial on frequency variation circuit using 555 timer The list of components used in this circuit design 555 IC, power source, resistors, capacitors, variable resistor, ground, and oscilloscope. Multisim is a suite of EDA tools that will assist design engineers in their circuit simulation and design flow. Let us start the circuit design using the multisim tool. The table below depicts various frequencies for different values of the variable resistor. This tutorial will help, how to simulate the circuit shown below using the NI multisim tool. To overcome this, we can use a variable resistor. If we change the value of resistors, the frequency varies at the cost of sacrificing the duty factor. In a traditional circuit design to keep the duty factor constant, and change the frequency continuously, can be achieved through a variable capacitor. In this circuit design tutorial, a 555 timer to be used for frequency variation circuit application. They find potential use in numerous applications such as time delays and oscillators. The 555 timer IC got the name due to the three 5 kilo-ohms resistors used in the voltage divider network. The 555 timer, one of the most frequently used integrated circuits by design engineers for novel circuit designs.
