Arduino Jobs

I have a project on Arduino (exapmle Mega 2560 ). The Arduino should act as a cash receiver and send exactly the amount that I deliver via Bluetooth to the balance. I have a working code, but it only works on a few coffee vending machines. Where it does not work, it blocks everything with one code: #define CSH_ACK 0x0100 // Acknowledgment, mode bit set. I also have an insulator circuit. The f...
