You probably notice that at some points of the video, the popup-menu options go outside the recording area. Spacebar is again used to rotate components 90 degrees, and multiple items can be selected with ctrl+click. I then remove some component names which are not sorely needed, and change the location for the remaining ones to the center of the component. I then proceed arrange the components roughly to final layout, and add two 10-pin headers which will plug into breadboard. Like it’s schematic counterpart, also this tool is quite easy to use.įirst I change the grid to 5 mil so each step is half of the 10 mil breadboard hole spacing. In DipTrace Schematic Editor, I used File->Convert to PCB (CTRL-B) to get the components and connections exported to PCB Layout tool. The module circuit design has three right-angle trace corners - at 5v levels I am not sure how much that would matter, but if I did this again, I would fix that.Continuing from part 1 of this ATtiny2313 breadboard header with DipTrace -tutorial, I’ll now go through the PCB design. I might elevate the backside a little bit to have this sit on the floor at an angle, rather than sit flat. The two pieces are held together using 2" high "sign holders". A tip for anyone else trying to cut acrylic sheets - do it in a well ventilated area - the chemical odour is very strong, and lingers for a long time. I used a 9"x18" piece that I cut into two to make these panels. The top and bottom panels are 1/4" thick acrylic panels measuring 4.5"x18" each. In order to fit that into my V, G, S design, I built this potentiometer breakout board: The pins on a standard 10K 3-pin potentiometer are - G, S, V.
Right angled pin headers then helped plug in 3-pin and 2-pin dupont connectors from the individual modules to the appropriate analogue and digital locations on the arduino. The Mini Breadboard like units on the Arduino headersĪdditionally, also using Oshpark, I had printed six units of these mini-breadboards with 8-pin headers that I could then plug in directly on to the female headers on the arduino board. Three of these modules are on one side of the board, and three others on the other - so those are designed to be mirror images of this board. This allows me to daisy chain the modules and use a single 5V, GRN pin set on the Arduino for all six modules. On the top are 5v and Ground input pins (V1 headers) that also have a direct connection to another header on the other side of the board (V2). Here is what each module looks like (designed using DipTrace)

Thanks to the "Control Surface" library, the code for this was ultra simple.Įach module contains three 3-pin headers for potentiometer connections, and two 2-pin headers, one for the toggle button (foot operated), and one for the LED showing whether or not that toggle is currently engaged.

I also had printed mini-boards to go on top of the arduino headers in lieu of full sized shields. Six mini-circuits were designed to be identical - keeping the design exactly the same for these helped keep the costs low - even if some modules used less than the 3 potentiometers, or no digital connections at all in some cases. This somewhat modular device was built with each 'module' dedicated to one pedal. I was looking to build a MIDI controller that I could stomp with a foot to toggle individual processing units on/off, and to also carry a few potentiometers that could change the parameters of these processing 'pedals'.
