Hello, I am a Telecommunications and Electronics Engineer with deep knowledge in systems with microcontrollers and Arduino. I can make your system using an interactive simulation software called Proteus (from Labcenter Electronics). Proteus has all the components we need (Arduino board, transistors, resistors, buttons, serial port viewer, LCD screen, etc.). I have developed similar projects.
I offer you a guarantee over everybody. I CAN MAKE YOUR SYSTEM BEFORE MILESTONE PAYMENT, this way YOU CAN SEE THE BEHAVIOR OF YOUR SYSTEM BEFORE BUYING IT. I need to know that you will hire me; we can follow the following steps:
1-) We agree on every little detail. I like to spend a lot of time on this step.
2-) I make the system just how you need it, and I send you a video with the simulation.
3-) Once you have seen the simulation, if you are satisfied with the system, you make the milestone payment to me, I send you the project, code, schematic, bill of materials, assembly instructions, etc.
4-) You verify the project and release my payment.
Please contact me in the chat; you will not regret it. I can implement any logical behavior that you need, giving you the best cost-benefit relationship.
Best regards.
