Hello,
This is my first semi large arduino project. I have some programming knowledge, some C++, Java, HTML so I am not new to syntax and coding. Hardware side of things I understanding cabling, wiring, and networking, that all being said I am new to this world called arduino lol. Now the fun stuff.
I am trying to create a automatically lifting shelf when an RFID is triggered, using a lift servo. Basically when someone puts the RFID tag on the receiver this triggers the servo to extend raising a otherwise hidden shelf. Revealing something inside.
Now the fun stuff. Arduino has an output of 5v the servo has an external power supply of 15v I have no idea how to bridge that gap, or how I would trigger the power supply at the correct time (when RFID is scanned). I am not sure how I would wire the servo onto the UNO board, or how I would program it correctly.
Some info on the servo. 15v power supply, it also has an up down switch installed inline. There are only 2 wires coming from the servo + -, upon removing the switch and testing out the way the servo worked I learned that Red = +, Black = -, when power is supplied the piston raises. To lower the piston if I reverse the way they are wired meaning Red = -, Black = +, the piston then retracts.

The RFID I am planning to use was just one that I purchased with an ELEGOO sensor kit. I figured for this project I would try and keep it as sensor compatible as possible.
Please help with anything you can as I am really excited to dive into this.
