After that we screw the slider potentiometers and the same for the rotary potentiometers too, and do not forget to put the potentiometers cavers so using theme will be easier for you.Īfter that we need to solder some wires in order to connect these controllers to the board. Now we have the PCB ready and all the components soldered very well, Now we need to place the push buttons each one to its placement in the top side of the bow, it will be so handy placing these push buttons. You can also download the Gerber file for this circuit from the download link below in the case you want to place an order for the same circuit design. with them reliable platform all what I need to do is some simple clicks to upload the gerber file and set some parameters like the PCB thickness color and quantity, then I’ve paid just 2 Dollars to get my PCB after five days only, what I have noticed about JLCPCB t his time is the " out of charge PCB color " it means you will pay only 2 USD for any PCB color you choose.Īs you can see in the pictures above the PCB is very well manufactured and I’ve got the same PCB design that we’ve made for our main board and all the labels and logos are there to guide me during the soldering steps. JLC is a professional PCB manufacturer featured of large scale, well equipment, strict management and superior quality.Īfter making the circuit diagram I transformed it into a PCB design to produce it, in order to produce the PCB, I have chosed JLCPCB t he best PCB suppliers and the cheapest PCB providers to order my circuit. for various of 1-layer, 2-layer or multi-layer PCBs. The annual production capacity is 200, 000 sq.m. With over 10 years of experience in PCB manufacturing, JLCPCB has more than 200, 000 customers at home and abroad, with over 8, 000 online orders of PCB prototyping and small quantity PCB production per day. JLCPCB ( Shenzhen JIALICHUANG Electronic Technology Development Co., Ltd.), is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production. We have all these controllers connected to an Arduino Nano board which has all the necessary I/O pins to hold these inputs together, and through its USB connector it will be easy to send instructions from the controller to the software side, by the way I’ve picked my own Arduino nano from webstore where you can get this Arduino and more other electronic devices with some special offers, and I recommend this webstore as a supplier, so go there and check it there is lots of cool stuff out there.įor sure in order to make a better appearance for our MIDI controller, I have designed this box considering the size for the push buttons and the potentiometers and through a CNC laser cutting process I can produced the designed parts for my project. In this tutorial we will take in charge the hardware part and we will create a Controller keyboard which has 12 push buttons for digital control and 6 potentiometers for an analog control so it is obvious that all the buttons will be used to display the notes and the potentiometers will control things like sound volume tone etc.
