26 de ago. de 2020 · This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in digital signal processing (DSP) and electronics labs. The author’s prototype is shown in Fig. 1.
This tutorial shows how to make a simple waveform generator by using the DAC features of the Arduino Due board. With push buttons, you will be able to choose a waveform shape (sine, triangular, sawtooth, or square) that we will send to to send to the DAC0 and DAC1 channels and change the frequency of the generated signal with a potentiometer.
4 de dez. de 2018 · In this tutorial we learn how quickly and easily we can build our own Arduino based Function generator or Waveform generator, which 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 change that in the ...
This waveform generator is powered by an Arduino. It outputs four waveshapes: sine, triangle, pulse, and saw, each waveshape ranges in frequency from 1Hz-50kHz. The frequency, pulse width, and overall amplitude (gain) of the waveforms is controlled by three potentiometers.
The Arduino IDE provides certain functions to generate a square wave at a particular frequency which is make use in this project. The functions are namely tone() and noTone() for start generating a square wave at a particular frequency and to stop the square wave respectively.
* Precise: 1mHz steps frequency range. As accurate as the Arduino crystal. * Easy operation: waveform and frequency settable with single rotary encoder * Wide range of amplitudes: millivolts to 20V * 20 pre-defined waveforms. Straightforward to add more. * Easy to make: Arduino Uno or Nano plus standard components
The circuit is very simple, Arduino nano, I2C OLED display 128 to 68 pixels, 3 transistors and three buttons, two of buttons are responsible for frequency adjustment, and the third button turns ON the output signal.
