A stock Arduino isn’t really known for its hi-fi audio generating abilities. For “serious” audio like sample playback, people usually add a shield with hardware to do the heavy lifting. Short of that, ...

The project is an experiment to illustrate that an Arduino can be used to create a real-time audio processing wherein the first set of examples alter an incoming audio signal to an audio output and ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...

A popular tool in chiptune software like LSDJ allows the user to draw a waveform and use it as the basis for a wavetable synth. It’s fun and it can produce some great bleeps and bloops. [Kevin] has ...

CleO is a touch-enabled display shield from FTDI Chip. With this intelligent, simple-to-program, full color TFT display board, engineers of all experience can develop imaginative and compelling human ...
