It requires an operating voltage of 12 V and delivers sine 22206 square wave signals. Many attempts have come out with this simple circuit. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

Function Generator with XR2206

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where zr and current must be monitored. It also analyzes transistor’s characteristics such as voltage and gain.

On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with alligator clips.

At pin 3 to set the exact medium voltage and the output 2206. With a pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to and may include a range of 10 Hz to 20 kHz sweep.

It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.


With the component values shown datashheet, the overlapping frequency ranges are shown in the following table: All required circuit details are shown in the datasheet.

The capacitor C and the power to determine the frequency at pin 7. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. But there are some points that could improve it take to build an almost professional function generator.

The actual sample structure differs in some details from the data sheet. Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses an ATmega as a frequency counter and to drive an 8-digit 0.

Arduino – XR Function Generator

Instead of the sine wave output is obtained after opening of S1 a triangular output wave. A common function generator provides sine, for example, triangular and square waves. With the frequency-determining capacitor of 0. Frequency control The frequency range is controlled with the timing capacitor connected between pins 5 and 6 of the XR and the timing resistors VR1, VR2 and R2 conencted in series between pin 7 and v. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.

Function Generator with XR It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.


The frequency must be adjustable and at least cover the low frequency range.

The additional output at pin 11 also delivers a square wave with the same frequency. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.

You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. Datashset data sheet provides complete basic circuit for a simple function generator.

Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The low-cost IC XR provides datasneet very simple function generator with only a few external components.

The output waveforms can be both amplitude and frequency modulated. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by dataaheet performance and health of electrolytic capacitors. The sample design renounces everything that is not absolutely necessary. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice.
