Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

Casey Halverson has launched a new piece of Arduino compatible hardware he has designed and built called the Arduino HamShield. That is capable of enabling your Arduino project to communicate with ...

This product is courtesy of It was super easy to make this mobile tracked platform and radio-controlled useful for building ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

This unconventional Arduino-based FM receiver is the result of one such inventory overflow, and even though it may take the long way around to listening to NPR, [Kevin Darrah]’s build has some ...

Arduino enthusiasts may be interested in a new thumb-sized radio-equipped Arduino Leonardo development board created by Doug Lyon. Watch the video below ...

Short-range radio specilaist LPRS has introduced a stacked module that allows Arduino boards to communicate wirelessly with other Arduino boards or PC hosts. The system uses the supplier’s easyRadio ...
