The Arduino Guitar Pedal is a digital multi-effect pedal based upon the Lo-Fi Arduino Guitar Pedal originally posted by Kyle McDonald. I made a few ...
You will need: (x1) Arduino Uno REV 3 (Radioshack #276-128) (x1) Make MakerShield Prototyping Kit (Radioshack #276-138) (x3) 100K-Ohm Linear-Taper Po...
Break the male header strip down to fit properly in the Maker Shield kit. An easy way to do this is to insert the end of the strip into each of the A...
Insert the male header pins into the Maker Shield and solder them into place.
Print out the attached template on full-sheet adhesive paper. Cut out each of the two squares. (The file has the pattern repeated twice in case to o...
Peel off the backing of the adhesive template and stick it squarely on the front of the casing. Drill all of the crosses with a 1/8" drill bit. Star...
Attach three 6" wires to each of the potentiometers. For simplicity's sake, you should attach a black ground wire to the pin on the left, a green sig...
Attach a 6" black wire to one of the inner pins. Next, attach 6" red wires to the 3 outer pins both to the immediate left and right of the black inne...
Start to build the circuit as pictured in the schematic. To see the schematic larger, click the little "i" in the upper right-hand corner of the image...
Cut out two brackets using the template file attached to this step. They both should be cut out of non-conductive material. I cut out the larger base...
Place the rubber bracket on the inside of the case so that it aligns with the drilled holes. Insert the potentiometers up through the rubber bracket ...
If you use long shaft potentiometers or rotary switches, trim them down such that the shafts are 3/8" long. I used a Dremel with a metal cutting whee...
Insert the foot switch into the larger 1/2" hole and lock it in place with its mounting nut.
We will be using stereo jacks for what is fundamentally a mono circuit. The reason for this is that the stereo connection will actually serve as the p...
Insert the two audio jacks into the two holes in the side of the case and lock them in place with their mounting nuts. Once installed, check that non...
Wire one of the outer pairs of the DPDT stomp switch together. Wire one of the jacks to one of the center pins on the switch. Wire the other jack to ...
Trim the wires attached to the components installed inside the case to remove any slack before you solder them to the Arduino shield. Wire them to th...
Affix the cork mat to the inside of the case's lid. This will keep the pins on the Arduino from getting shorted on the metal of the case.
The code that this pedal is largely built upon ArduinoDSP which was written by Kyle McDonald. He did some fancy things like mess around with the regis...
Attach the Arduino to the shield inside the case.
Plug in the 9V battery to the 9V battery connector. Carefully situate the battery snugly between the DPDT switch and the Arduino.
Put the lid on and screw it shut.
Place knobs onto the potentiometer and rotary switch shafts. Lock them in place by tightening the set screws.
Plug in your guitar to the input, connect an amp to the output, and rock out.
