The idea is to solder up some pre-made indicators with integrated resistors to save space on the breadboard when prototyping — instead of four slots, you only use two per LED. This is about as ...

[Aniss Oulhaci] demonstrates this with a simple HF SDR receiver built on a breadboard. An Arduino is used to control the SI5351 clock generator, which in turn is controlled by the same program ...

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 ... Write a program that changes ...
