This is something i’ve been working on for a couple days and finally got something worth showing. After a while using Radio Frequency Links in some projects i realized that many messages are lost and it requires you to send them over and over again until it reaches the destiny and does what it is supposed to do. I then decided to do something about it and since i know i’m going to lose a few messages in the air at least send it again in a transparent way so it doesn’t bother me. In a few words this is an implementation of a protocol that guarantees that a message sent over a RF Link will get to its destiny no matter what. This implementation is based on RF Links, Arduino e Java. At the end of the explanation of the protocol there’s an example of where it can be usefull, so, let’s get it started.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
