Hello, I am Telecommunications and Electronics Engineer with deep knowledge on systems with microcontrollers and Arduino. I can make your system using an interactive simulation software called Proteus (from Labcenter Electronics) Proteus has every instrumentation and animated electronic component wee need (like Arduino board, resistors, push buttons, active buzzers, etc) I can implement any logical behavior you need, you just dream, I make it real. I have developed similar projects using buzzers, please, see my portfolio.
I give you a warranty above every body I CAN MAKE YOUR SYSTEM BEFORE MILESTONE PAYMENT and I send you one video with the simulation, that way YOU CAN HEAR YOUR SOUND BEFORE PAY MY SERVICE. We can do the next:
1- We agree every little detail about project, I like to dedicate a lot of time to this step, you send me a sample of the melody you want hear.
2- I make your system and I send you one video with the simulation, that way, you can hear your sound.
3- If you are satisfied with your system (and only if you are satisfied) you make the milestone payment for me, I send you the project, code, schematic, assembly instructions, etc.
4- You check the project and release my payment. Anyway else, you can suggest me any modification and I correct it.
Please, contact me in the chat, you will not regret it. I need to know details about your project. I will give you the best cost - benefit relationship.
Best regards
