Greetings, we are a group of electronic engineers, instrumentation and computers.
We have experience PIC microcontrollers (series 12F, 16F, 18F, dsPIC30F, PIC32), Arduino (we have Arduino Nano, MEga2560, Uno), we develop PCB with Eagle, Proteus, Ares, we have programmers / debuggers ,.
We also have experience in Java, JavaEE, Spring Boot, Sql, NoSql, Docker, Servers, continuous integration, Blockchain Experience, Ethereum and Bitcoin, and Token ERC20.
We can develop your Sketch for the arduino, we have the RGB Leds and a distance sensor by Ultrasound, to make the test in real and make the adjustments .... Or you could also indicate which would be the proximity sensor that you intend to use .
We hope you accept our proposal.
Times are referential, depending on the complexity of the project.
regards
