Development of electronic devices

It is necessary to develop and manufacture a prototype device based on the AVR or Arduino microcontroller. The device is a pulse generator with specified parameters. The device is controlled via bluetooth from a mobile phone. The mobile phone program is ready. There is also an electric principle scheme and a board in the altium designer. It produced 2 printed circuit boards and soldered components on one of them. It is necessary to check the electrical circuit, if necessary, remake the circuit board, unpack the components and write a program for the microcontroller.
