Oct 19, 2024 · I am facing issue in my project of function generator which can generate sine, square and triangular wave using AD9833 module and Arduino uno. Code is works properly and it generates square wave but its not generating sine and triangular wave form. Here i am using this libraries: Here is the code: #include <AD9833.h> // Library for AD9833 Module #include <Wire.h> // Wire Library for OLED # ...

Jan 22, 2021 · hello there. 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. well i wrote 2 codes, the first one using the principe of ...

Mar 31, 2014 · Hi sir this is my first time posting here, give me some advise on how to make my project (a waveform generator) that generates 20hz-20Mhz. i saw one tutorial which is a Arduino-due Simple waveform generator with maximum frequency of 170hz. FunctionGenerator.ino /* Simple Waveform generator with Arduino Due * connect two push buttons to the digital pins 2 and 3 with a 10 kilohm pulldown ...

Feb 13, 2024 · I used AI to generate parts of this code, I am wondering if someone that has access to an oscilloscope and 4 potentiometers would be able to set it up and test it out for me. I am going to try it on my Nano later on, but i have 0 faith in it. Any adjustments or recommendations on the code are greatly appreciated. int pwmPin = A6; // Connect the potentiometer for PWM to analog pin A6 int ...

Mar 18, 2017 · Hey, while experimenting with operational amplifiers, I realized I need some form of visual representation of the voltages and a easy-to-use function generator would also have been nice. Since an oscilloscope and a function generator would have been overkill for my experiments, I created a arduino based one on my own.

Oct 29, 2018 · hello, everybody, I am trying to build a function generator using AD9833 with Arduino Uno, I have found a good reference for this project and I have used its code but unfortunately, the Arduino programming continuously t&hellip;

Apr 11, 2025 · I have now tried 2 different versions of rob tillaarts function generator library found and now installed from the library manager. version 0.7.1 and 0.4.3. The latest release is 0.3.0, see GitHub, so apparently there is something strange. Can you post the first 10 lines of the .h files of the libraries you use?

Mar 22, 2009 · Hi i want to make a simple function generator with arduino. Anyone have a good program for it. I would like it to go at least up to 140 khz and try to have it produce a square wave. And if the is i circuit i could hook up to the outside of arduino which can turn the output into Ac power that would be great!

Nov 14, 2022 · Portable Function Generator on Arduino. Portable Function Generator on Arduino: Function generator is a very useful tool, especially when we are considering testing our circuit's response to a certain signal. In this instructable I'll describe …

Aug 30, 2013 · Hi to y'all, First let me say, i'm not an electronics wizkid :), so don't start shouting at me, lol. I'm in need of a real analog blockwave generated with PWM, so simple turn 0-5V PWM to -2.5-2.5V.(or any similar voltages, i presume i can amplify it later.) So my idea was to build this function generator : All is fine except i do have an LM380 instead of a …
