本文介绍经常在电吉他使用的失真效果在Arduino UNO控制板的上的实现。数字电位由Arduino的控制（微控制器）是一个进步，并能产生令人满意的结果。一个三阶段的失真电路的复杂电路与模拟电位改为由微控制器控制。-This paper describes the distortion effects often used in an electric guitar. Distortion is an

added effect in an electric guitar, which compresses the peaks of the sound waves produced by the musical

instrument, to produce a large number of added overtones, which here is done by rigging up a circuit in

collaboration with the Arduino UNO circuit board. The digital potentiometer controlled by the Arduino

(microcontroller) was an improvement and was able to produce satisfactory results, as compared with the

analog potentiometer without the Arduino control. The complex circuitry of a three-stage distortion circuit

with the analog potentiometer was replaced by a digital potentiometer controlled by a microcontroller, with

better results. This variable-gating distortion pedal has an added advantage of being compact, light, and

inexpensive.
