Development of a controller for a water dispenser
602 USD It is necessary to develop a control board for a water dispenser, with the possibility of later copying it for serial production. The project will need to be supported and modernized in the future, so a motivated person for long-term work is required. Preference will be given to a developer with experience in this field. If there are ready prototypes, we are ready to consider them.

Hello!
I am engaged in embedded development (ESP32/STM32/Arduino). I have already implemented 2 projects on your topic — I have practical experience and developments.
I will do it quickly and accurately: connections/protocols/logic/debugging.
I am ready to start immediately.
The price and deadlines are indicated preliminarily. I can provide exact details after clarifying the specifications.

Good day. There is a ready project of a kvass machine. It is implemented on ESP32-S3 and a 7" touch display. Data transmission occurs via the GSM module SIM800. The bill and coin acceptor operate in pulse protocol. We are now transitioning to the MDB protocol.

Good day! I am interested in your project for developing a controller for a water dispenser. I work with ESP32 microcontrollers in the Arduino IDE environment. I have experience in developing both hardware and software for IoT devices, including controlling pumps, sensors, and displays.
To better assess the scope of work and prepare a quality solution, I would like to clarify:
What microcontroller or platform is preferred for this project?
What main functions should the controller perform (water supply control, payment processing, display, communication, etc.)?
Is there already a basic schematic or reference design?
Is support for specific protocols or interfaces needed (UART, I2C, SPI, RS485, etc.)?
We can just discuss it in messages beforehand.
