Hello there,
I read your project description. I see that you are sharing very limited information. I have 5 years of experience in the field of IoT. I have developed many real time working projects with RPi and arduino. New generation touchscreen smart vending machine, Unattended POS device, Vending telemetry device are some of them. In these projects, I developed all processes such as electronic circuit design, material selection, coding of processors, project architecture, RPi selection, image creation, and Python script development to work on. If we meet, I can share my references. The projects I have developed are active 24/7 in the field. I can develop your project from scratch to production level or I can advise you in this process. I will learn about your project requirements and revise my proposal after the meeting. Waiting for you to start a chat for details.
Kind regards,
Fatih Saral
