I'm opening a perfume spraying vending machine and I need to link 5 solenoids to raspberry bi. Is it easy or should i hire someone to do it? I live in vietnam and the language barrier is a setback for me.
Extra information: i need to connect raspberry pi to 5 solenoids that are connected to 5 different bottles of fragrances for a vending machine. when a customer for example, chooses the Sauvage perfume, that connected solenoid will open and spray a small amount of perfume etc. equipment being used: Parker 2-Way Solenoid Valve (Series 40), Kamoer KVP-12A Diaphragm Pump, 1N4007 Diode, SainSmart 4-Channel Relay Module,
