Build your own Optically Isolated 8 DI Arduino Shield
MakerIoT2020 Jul 22,2021
All of us Makers like to tinker with stuff, and in this process, we may find ourselves thinking about how to connect device A to my Arduino… Device A may operate at a different voltage from the Arduino, and may thus damage it badly….Many different solutions exist to do this, but, many of them, like relays, can be quite bulky, increasing the overall size of your project, as well as putting bigger demands onto your power supply unit.Having worked in the Industrial Automation sector for a few years...

Arduino Voltage Controlled Wavetable Oscillator
Guidolin Jul 22,2021
Lurking for a simple digital filter for my modular synthesizer, I got aware of the existence of a library capable of turning any arduino board into a wavetable oscillator... WHAAAT!I could not resist (how could I! Korg DW8000 is still one of my favourite synthesizers!) and immediately started developing a pcb for an eurorack wavetable oscillator based on Mozzi library.In the following I will show you how I designed my voltage controlled wavetable oscillator prototype for modular systems.Fea...

ESP-32 board on Arduino footprint
Rafal Witczak Jul 15,2021
ESP-WROOM-32 (or ESP32-SOLO-1) development kit with Micro-USB port, DC Input and ESP-PROG interface.Based on Arduino Uno/Leonardo footprint, so (apart from interesting appearance)allows to use stands and (partially) enclosures from original Arduino.Note: It's not an Arduino clone, so it's not compatible (neither electrically nor physically) with Arduino shields.Functionally it's evaluation board like ESP32-DevKitC.
