Software serial requires a lot of help from the Arduino controller to send and receive data, so it's not as fast or efficient as hardware serial. Danby 5000 Btu Portable Air Conditioner Installation. The Arduino Mega has four hardware serial ports that can communicate with up to four different serial devices. Updated 2017-05-13 This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost.

This miniature version of the Arduino uses a processor. Compatible [ ] Although the hardware and software designs are freely available under licenses, the developers have requested that the name 'Arduino' be and not be used for derivative works without permission. The official policy document on the use of the Arduino name emphasizes that the project is open to incorporating work by others into the official product. As a result of the protected naming conventions of the Arduino, a group of Arduino users forked the Arduino Diecimila, releasing an equivalent board called Freeduino.

The name 'Freeduino' is not trademarked and is free to use for any purpose. Several Arduino-compatible products commercially released have avoided the 'Arduino' name by using '-duino' name variants. Footprint-compatible [ ] The following boards are fully or almost fully compatible with both the Arduino hardware and software, including being able to accept 'shield' daughterboards.
