The topic of my bachelor’s thesis is the design and the construction of the pedal effect used by the Arduino Due, which is supplemented by the possibility of controlling through the internal web interface, which is mediated by the modul Arduino Ethernet Shield. The following effects are included: echo, tremolo, vibrato, chorus and flanger. For editing the guitar signal in order to interact with AD microcontroller converter, is used the input filter preamplifier circuit. In order of editing the output signal from Arduino is used summing and filtring output circuit for the guitar amplifier. The basic component for these circuits is operating amplifier OPA1644. The goal of this thesis was to create the proposal of the connection schemes, print...
