Dec 4, 2018 · In this article we will learn how quickly and easily we can build our own Function generator using Arduino. This function generator a.k.a waveform generator can produce square wave (5V/0V) with frequency ranging from 1Hz to 2MHz, the frequency of the wave can be controlled by a knob and the duty cycle is hardcoded to 50% but it is easy to ...

Jan 6, 2021 · In this article we are going to building a simple Signal Generator with Arduino and AD9833 DDS Function Generator Module which can produce sine, square, and triangle waves with a maximum frequency of 12 MHz at the output.

Jan 22, 2021 · i am trying to make a function generator using atmega328 ( arduino uno ), i used a resistor ladder R-2R as a digital to analog converter and a timer to generate time event that every interrupt of it will move to the next sample and write that value to the PORTD ( where the dac is connected ) and some printing on lcd I2C.

The AD9833 is a low power, micro controller programmable function generator capable of producing sine, triangular, and square wave outputs. The output frequency and phase are software programmable, allowing for easy tuning.

Arduino library to generate (numeric) wave forms for a DAC. This library presents a class for a function generator in software. It is typical used to control one or more DAC's. To maximize signal quality one has to apply all (or most) processor power to calculate new values over and over again to get enough resolution.

Waveform generators (also called function generators) are useful for testing and debugging circuits. I often use them to test the frequency response of electronics components like op amp and sensors. This waveform generator is powered by an Arduino.

In this instructable I'll describe the building sequence of small, easy to use, portable function generator. Features of the project: Fully digital control: No need for passive analog components. Modular design: Every sub-circuit is a pre-defined easy to use module. Output frequency: Available range from 0Hz to 10MHz.

Apr 20, 2014 · This is a Functions Generator to be used to drive physical variables either directly by voltage variations using PWM or by means of a control loop implemented in the Arduino code.

May 14, 2011 · Before we start with that – what is a function generator? A function generator is a circuit that generates some kind of waveform. There are four main types of waveform – the square wave, triangular & saw-tooth waves, and the sine wave. There’s a good article on function generators on wikipedia.
