One of the best ways to learn about radios is to build your own, even in the age of cheap SDR dongles. [Aniss Oulhaci] demonstrates this with a simple HF SDR receiver built on a breadboard. An Arduino ...

The project utilizes an Atmel8 AVR as the heart of the board to create an Arduino compatible breadboard. The USB to serial communication board used in this project utilizes a FT232 USB breakout board.

If you're looking to make yourself somewhat more productive on this lazy weekend, and you've got an Arduino or two collecting dust, we've got just the thing to add line after line to your dwindling to ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).

Here’s a no-PCB Arduino that doesn’t obscure the DIP footprint of the AVR chip. It’s built on an ATmega88 chip, and includes a programming header, reset button, a couple of filtering caps, and an LED.
