The space was very limited, so it was really a challenge, but now it works. I achieved this by splitting the wood support in 3 parts which were connected in sequence by long screws from the bottom of the pipe. It can look complex but after all is not so much… the difficult part was to make the design of the mechanical parts (2 ball bearings 1 inch diameter on the U aluminium frame, the wooden support, the spring and the potentiometer) so that it was possibile to assemble all inside a 90° PVC bent pipe… It sits with a bunch of pins on top of the arduino like other shields, but it is not fixed there. Encoders and displays will get their own connectors (which i am waiting for) Furthermore, the complete board can be separated from the controller board. There is probably a missunderstanding here: Switches and LEDs signals can be connected and disconnected at will using the blue connectors. So it’s up to you of course, and please keep updating with your progresses!Īnd grouping wires so that they follow some “tidy” (ehm more or less tidy) paths, the result appeared quite reasonably good for me. The advantage of a complete wiring to a dedicated board is that you can more easily dismount a device and reconnect it to its appropriate connector on the board, and makes also easeier to handle the connections between the board and the arduino. I encloase a picture of the wiring, it was not yet completed in that picture, but gives an idea of how I made it. Using different lenght wires (I used a Dupont crimping tool for the terminals) and grouping wires so that they follow some “tidy” (ehm more or less tidy) paths, the result appeared quite reasonably good for me.Īt that point was almost unrelevant to draw the wires to an intermediate board or directly to the Arduino. This reduces the wires to the board to the single pin from each device to the board. The same was done for the +5V to the leds and in your case probably to the OLEDs. The OLEDs will be fantastic to see in action, please post a picture when they’ll be operative.Ībout the wiring, I can only say what I did (considering that using 2 wires or more eg for all the controls of my overhead even if I had used a customized board would have caused a real haystack - that happened in my first version) so I decided to have a “running ground wire” going all over the panel, with connection spots where I connected all the negative pin of all controls as buttons, switches etc. Very good NoPiggies, that looks awesome! Of course the board you designed is very tidy and well organized and give surely a “plus” to your project.
