Maixduino: Pan-Tilt Servo Control with MaixPy

Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up and down in a vertical plane. Tilting the camera results in a motion similar to that of someone raising or lowering their head to look up or down. [1] In cinematography and photography, Panning means swivelling a still or video camera horizontally from a fixed position. This motion

MaixPy #3: Maixduino Analog-To-Digital Converter (ADC)

An ADC converts a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal. The conversion involves quantization of the input, so it necessarily introduces a small amount of error or noise. Furthermore, instead of continuously performing the conversion, an ADC does the conversion periodically, sampling the input, limiting the allowable bandwidth of the input signal. [1] In this tutorial, I am
