Arduino Multiplexor – MUX INPUTS & OUTPUTS – ANALOG and PWM
https://www.youtube.com/watch?v=Dco6jo9xgAo
Multiplexers and demultiplexers are devices that allow us to control a greater number of devices with a smaller number of inputs or outputs. We can use these devices to expand the number of inputs and outputs of a processor like Ardunio.

YouTuber Mr Innovative has created a simple wire harness wrapping machine that takes tape and quickly spins it around a bundle of cable.
This wrapping machine makes wire harness creation a breeze
https://blog.arduino.cc/2022/09/05/this-wrapping-machine-makes-wire-harness-creation-a-breeze/
Many products require the use of wire harnesses, which are essentially bundles of cabling that connect one subsystem to another, such as a car engine’s sensors to the ECU. DIY projects can also find themselves needing one, but having to manage the wiring without tangles or unwanted bends can be a challenge.

This library lets your Arduino act as a voice synthesis processor.
Talkie Library Makes Your Arduino Speak Like It’s 1985
https://embeddedcomputing.com/technology/open-source/talkie-library-makes-your-arduino-speak-like-its-1985
Perhaps you remember the early voice synthesizers of the 1980s, which “spoke” in a muffled, marginally intelligible tone. Audio data storage was based on a linear predictive coding (LPC) format, and played back with a voice synthesis processor (VSP).
Texas Instruments’ Speak & Spell educational toy was perhaps the most iconic device that used this sort of technology, and if you’re nostalgic for this “soothing” voice, you can generate this type of speech using an Arduino and the Talkie library.
This library, which was first published in 2012 by Peter Knight, appears to now be updated and maintained by Armin Joachimsmeyer, linked here by Arduino. It takes LPC sound files, and uses an Arduino to act as the VSP.

Arduino UNO Guitar Pedal © CC BY-NC
https://create.arduino.cc/projecthub/electrosmash/arduino-uno-guitar-pedal-b2ba96
pedalSHIELD UNO is an Arduino UNO programmable guitar pedal. You can create your own effects and digital sounds.
https://www.electrosmash.com/pedalshield-uno
Specifications.
Based on Arduino / Genuino UNO (16MHz, 2KB RAM).
Analog stages using TL972 rail-to-rail operational amplifier.
ADC: 10bits.
Output Stage: 16 bits (2x8bits PWMs running in parallel)
Interface:
2 Configurable push buttons.
1 Configurable switch.
1 programmable blue led.
True Bypass Foot-switch
Connectors:
Input Jack, 1/4 inch unbalanced, Zin=0.5MΩ.
Output Jack, 1/4 inch unbalanced, Zout=0.1Ω.
Power supply: power taken from the Arduino UNO board.
The idea is to make it as easy as possible, the shield is programmed in C/C++ using the standard Arduino functions and software platform (Linux/Windows/Mac). All tools and programs are free/open source.
The complete project is Open Source Hardware, the design was done using KiCad, an open-source GNU free of charge electronic design CAD tool. All the project files, schematics, and bill of materials are public. The circuit can be broken down into 5 simpler blocks: Power Supply, Input Stage, Output Stage, User Interface and Arduino Connectors

Arduino Guitar Pedal
https://www.instructables.com/Arduino-Guitar-Pedal/
The Arduino Guitar Pedal is a digital multi-effect pedal based upon the Lo-Fi Arduino Guitar Pedal originally posted by Kyle McDonald. I made a few modifications to his original design. The most noticeable changes are the built-in preamp, and the active mixer stage which lets you combine the clean signal with the effects signal. I also added a sturdier case, foot switch, and rotary switch to have 6 discreet steps between the different effects.
The cool thing about this pedal is that it can be endlessly customized. If you don’t like one of the effects, simply program another one. In this way, this pedal’s potential is largely dependent upon your skills and imagination as a programmer.
