Sound Frequency Generator For Arduino

1 2 10kHz to 225MHz VFO RF Generator with Si5351 and Arduino Nano, with Intermediate Frequency IF offset 3 or -, RXTX Selector for QRP Transceivers, Band Presets and Bargraph S-Meter. See the schematics for 4 wiring and README.txt for details.

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 5V0V 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 program as well.

This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in DSP. Circuit diagram of the sine, square and ramp Arduino-based frequency generator is shown in Fig. 2. It is built around an Ardunio Uno board Board1, 162 LCD LCD1, two 10-kilo-ohm potmeters VR1 and

Joekutz over Hackaday.io created a simple wave generator using Arduino powered from 9V battery and produces amplified and non amplified signals. This generator uses the 8-bit resistor ladder , aka R2R, DAC with 0.0195V step, knowing that Vout of R2R DAC is V out V ref VAL 2 N Where N 8 hence 2 8 256 and V ref 5.0 V.

In Arduino Note Generator I update the project to play discrete notes. This is a simple way to map a range of sensor readings in this case 0 to 1023 to something else in this case a frequency between 120Hz and 1500Hz. The tone function generates a square wave at a certain frequency, which when fed through a speaker generates a simple

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. Circuit diagram of the sine, square and ramp Arduino based frequency generator is shown in Fig. 2.

Arduino Audio Frequency Generator. Back in good ol' 2012 the year the world was supposed to end, I posted some code for a simple Arduino controlled low-frequency oscillator LFO. It has made its way into some very interesting projects over the years, but recently I was asked in the comments if the code could be modified to have a wider

A basic Direct-Digital-Synthesis waveform generator outputs the amplitude corresponding to phase-values based on a phase_accumulator which is incremented by a phase_step at a frequency f_clock. Compared to other Waveform Generators using the Arduino uno which directly output amplitude values based on a time-step using a timer interrupt at 100

Arduino half-hour Beeping Timer. The Arduino beeping timer generates a beep tone with an interval of 30 minutes between each beeping sound. The beep sound has a duration of 3 seconds and a frequency of 1500Hz. Instead of the delay function, the code uses millis function to obtain the time. So between each tone, additional codes can be added to

Introduction. 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.
