* @brief Main sketch: Si5351-based HF receiver VFO for Arduino (ATmega328).

PIO_VFO1 is the basic PIO oscillation program; the display shows only the frequency and the step frequency. It uses a 128x32 OLED. PIO_VFO2 has no change to the PIO oscillation program; the display ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...
