Hi!
I can make research, write code and design custom PCB for your project using Arduino. It may include any SENSORS, IOT, MIDI Controllers, Computer Software interfacing and different Communication Protocols (SPI, I2C, UART, MIDI).
I can make and test prototype of your product and can provide PCB design for it for mass production.
i can also provide you IOT solution for your project like sending data to apps or website over internet so that you could control your devices from anywhere over internet.
At the end of project i will provide you complete arduino code including library files if required and circuit diagram that how you can connect them.
for more debugging, i will be available for online session to fix the circuit or code and let your project work.
