Good day, I have recently completed a raspberry pi project and it works 100%. It has 6 inputs (pulses) and at the moment I only use normal buttons to complete a circuit which act as a pulse.
I would like to make this a vending machine and I need a device that will be able to send 6 pulses as output (like pressing one of the buttons) to the raspberry pi and maybe have one input that will be able to put the payment system on hold while the raspberry pi is busy. The payment system (I am currently looking at the VPOS touch) will then be connected to the MDB and there would only be 6 options to choose from. One of the options should be chosen on the VPOS touch, paid for and then it should let the MDB send the correct pulse (one of 6 wires) to the raspberry pi which would then control the rest of the process.
Does anyone maybe have a suggested MDB board that would be able to do this and does this seem like a easy problem to solve? I am very new to this and any help will be greatly appreciated.
