Fast Analog Read on Arduino

The Arduino AnalogRead(pin) function is simple to use, but can’t be called faster than about 10 kHz. Audio needs sample rates closer to 40 kHz.

This post will be a notepad of resources and notes related to high speed analog input on Arduino.

Analog Read Library Performance Comparison

Arduino Analog Read – 10kHz
AVDWeb AnalogReadFast – ___ kHz
Manually Adjusting Prescaler – 1 MHz
