The trick is using a breadboard where each bus bar is connected to an IO pin on an Arduino Due. A program runs through each point on the breadboard, running a continuity test to see if there’s a ...

An Arduino Due forms the heart of the project, controlling a TEA5767 module, an SH1106 128×64 pixel OLED display and a rotary encoder. The sound signal is passed through an LM4811 headphone ...

Due to their high processing power, Raspberry Pi machines often require a power adapter, as most USB ports can't supply enough current for it to function properly. On the other hand, Arduino ...
