While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

Step 2: Set up Arduino with 433Mhz transimitter and receiver This link has a pretty explanation about datasheet about transmitter, and this one for receiver. After you read through the datasheets, you ...

Arduino 433 MHz Receiver/Transmitter Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.
