One port to role them all.

Learn how to submit your Arduino-based project. It may even get featured on the Arduino social channels!

But why?

Program Arduino boards without using traditional USB cables.

As ESP8266 works on 3.3V and not 5v, it is important to perform this task.

This is a very simple way to control a 3-phase AC installation in a delta configuration.

Based on Blockly and BlocklyDuino, here's a multilingual enhanced version with supervision, upload, multi-level blocks, etc.

Clock LCD display adjustable.

This code enables you to make an accelerometer and gyroscope give the best results.

My second meetup explored I/O while building a sequencer. This is the project writeyp for that event.

A simple method to notify a problem is to use email, It’s very usefully and simple to share, so I created a library to do it.
