Hello. I am a computer engineer and electronic specialist, with several years of experience in various programming languages, and in my own DYI assemblies, as well as third-party projects with Arduino and its boards with sensors of all kinds. I can develop the project you demand without problems. I advise you the extra components you need for the assembly. I guide you in the assembly if necessary and most importantly, I tailor the program according to your requirements. For later, if you are interested, I can make your own design of a PCB that integrates an arduino model with the necessary components for what you demand. For example, accurate clock, SD storage, even with a view to moving the data to the cloud. I work seriously. I carry out electrical design, electronic diagram, PCB design and provide the file with the requested programming to be loaded on the Arduino board, I carry out the guidance and supervision of the load and implementation of the solution. You can see one of my latest works. A stopwatch for rallies. If you are interested in carrying out your project you can contact me and we will talk.
