Companion of a raspberry mini computer with a cashcode recipient
Choose an axis for a mini computer;
Connect and set the inet using a 4G modem.- select from the ready (e.g. https://arduino.ua/prod2535-shild-3-h-rele-dlya-raspberry-pi) or design a 3 rally shild to connect the load of 250V, 10A to further manage the rally using a mini-computer;
- select from the ready and connect the analogous Hall sensor for further control using a mini computer;
Connect the validator to a mini-computer by CCNET protocol;
Choosing a development environment;
- Write a test software that will light the message of the found injected banknot, once every 30 seconds will light the message of the speed of rotation of the Hall sensor.Likewise, after the nomination will be determined, the banknotes will include one of the relay for 10 seconds.For instance, 10 UAH included, 10 seconds included, 20 UAH included, 2 UAH included, 50 UAH included, 3 UAH included.Consultation on the further development of the finished device.After the testing and disposal of the iron software will need to participate in the development of the prototype.
