Arduino Doorbell Phone

Ring a phone and create a wireless doorbell with an Arduino.


Bryan gives step-by-step instructions of how he converted a 1940's Swedish-made Ericsson bakelite original into a wireless doorbell...


This project combines a battery-operated doorbell, antique phone, Arduino, and subscriber line interface circuit (SLIC) to make a wireless doorbell. The Arduino project include phone restoration, creation of a custom doorbell button transmitter, modification of the receiver, workings of the SLIC, and description of the Arduino code. A 'Retro' hack project will be of interest to people who like to repurpose antiques.

Arduino as a 4 voice wavetable synth

Turn your Arduino into a 4 voice wavetable synth with only a few components...




DZL from GeekPhysical wrote a 4 voice wavetable synthesizer that is one of the more advanced software based synths for the Arduino.  It has wavetables included (sine, saw, square and triangle) and envelopes to create beats.
A standalone synthesizer made with only an Arduino and few components ..
No shield, no processing, only ARDUINO

Daisy Chaining Arduino via Serial Connections

How to connect multiple Arduinos together





Scott Lawrence from The Geodesic Sphere shows us how to daisy chain multiple Arduinos together via their serial ports.


.... "As part of the Animatronic Avian project, I need to have a way for the controller software/computer to send synchronized data out through all of the performers on the stage"

Arduino light organ

A Psychedelic light organ of 80s


Psychedelic light organ of 80s style, developed with an Arduino and a FFT library for the analysis of the signal obtained by an analog input.

The project uses a microphone to get the signal, which is then adapted to the analog input of the Arduino.
Also included is a power amplifier based on triacs and optocouplers.

Manage a menu and LCD display with Arduino tutorial

Tutorial : How to create a menu in Arduino LCD 



In this project we can find a library very flexible to create menus with Arduino. Only need a Hitachi HD44780 compatible LCD display, 4 buttons and 4 10k resistors. 
You can create the menu structure using such methods as addRight, addLeft, Add and AddBefore  to add the entries to the right, left, below or above other menu items. To browse an item other intuitive methods are used such as moveLeft, MoveRight, moveUp and moveDown
