We design small projects that combine an integration between hardware, software and fabrication. The app we're developing, is a free online wizard that assists you in the making process. As you can see below, we added a link to circuito.io which will redirect you to the pre-selected parts for your project. Follow the steps, finish up the wiring, and upload the test code to your Arduino. Once you make sure that everything is working, download the custom code for the project from the project page here on Hackster.io, and also the .STL files that you can adjust if needed, and 3D print.
Enjoy the process and let us know if you need any help.
