If we manage to charge and discharge the capacitor with the same constant current, then the voltage of the capacitor will become a triangular wave; that’s the crux of this circuit (Figure 1). Figure 4 ...

[Faransky] has created a very impressive Arduino function generator that doesn’t skimp on the features. Capable of generating sine, triangle ... device is a AD9833 waveform generator; with ...

Anyone searching for a function generator ... portable use: With external charging ability, ensuring that the device is portable and convenient. – AC and DC coupling for output waveform ...

That’s just what [rgco] did to build this nifty arbitrary wave generator. The build improves on prior work by [rgco] with the Arduino Uno ... per second, using the DMA and PIO subsystems ...
