What do you pick when you want to make something with a nostalgic touch? A radio, of course! Well, the project presented here is about building a compact Arduino FM Radio with the help of an ...

Connecting the NRF24L01 can be tricky - you have to pay attention to the layout of the pins, adjust them to match those from the library and add a capacitor. This board solves all that, and it already ...

3D print and build an Arduino Pistol-grip Transmitter for controlling Remote Control cars. Today, we’re assembling and wiring a 3D printed Arduino-based pistol-grip radio transmitter that operates ...

eRIC Nitro features an ATmega328 AVR microcontroller with Arduino bootloader and a low-power eRIC radio module operating in the ISM band (433 MHz with eRIC4, 868 or 915 MHz with eRIC9). The MCU and ...

The goal for this project is to use RF technology to control an Arduino powered car wirelessly. Ideally, this system could be placed into any hobby RC car and be able to control the vehicle with the ...

Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...

While designing an internet of things (IoT) project that also required a long radio-frequency link, it occurred to me that there are pre-wired modules already built to do that. In fact, not only do ...

We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for ...
