An inexpensive DDS Signal generator based on the AD9851 module to generate sign wave of up to 70MHz (20-30MHz realistically). The module also has a built-in reference square wave up to 1 MHz, this ...

Arduino programs that allows manipulation of the Si5351 to produce a poor man's Sig Gen. Its a work in progress and there are a few improvements and a few bugs to be fixed. Caveat emptor. My original ...

Arduino nanoを使用してモジュラーシンセサイザー のDual Envelope generator (EG)を自作したので、その備忘録。 背景 自作モジュラーシンセの46作品目。 私はプリント基板（PCB）の設計をしたことが無かった。PCB製のフロントパネルを設計した事はあるが、電子部品を使用するPCBは設計したことが無い ...

The Arduino Mega2560 is based around the ATmega2560 8-bit, 16-MHz microcontroller. It has a total of 54 general-purpose input/output (GPIO) pins configured into six 8-bit and one 6-bit ports.

1. Arduino Board: The heart of the project. An Arduino Uno or similar board will work perfectly. 2. Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3.

This waveform generator is explicitly intended to support signal processing learning. This low-cost waveform generator can produce multi-frequency signals with high sampling precision and linearity ...

ERAsynth is an open source, crowd-funded project — now available on Crowd Supply — aiming to make multi-GHz RF signal synthesis accessible to everyone.

This research aims to create an arbitrary waveform generated by simulation to be observed using an oscilloscope. This waveform generator is explicitly intended to support signal processing learning.

Versatile low-cost audio signal generator and pulse generator (up to 4MHz) based on Arduino Nano MCU module.
