Clever Coasters

### DESCRIPTION ( Introduce yourserlf and your project)

Hello, My name is Rubba, and I am in my final semester of Computer Engineering. A requirement for my graduation is to build a capstone project that incorporates a PCB design. I decided to build a way for waiters to track the volume of customers cups through Wireless Communication and Sensor technology. It is a very IoT (Internet of Things), based project. 

### TECHNICAL DETAILS (With project photos)

Our main processor for each clever coaster will be the CC2650 microcontroller with built-in Bluetooth LE technology which will be soldered onto the PCB. This PCB needs to be interfaced with an external NFC antenna, and a weight sensor. Our weight sensor will be made by interfacing Velostat and conductive wire with a Voltage Divider. Through wireless communication the data sensed in the coaster will be sent over NFC to a nearby device which will then process and send that data over to the Waiter's screen. 

(Although it says CC2540, we have recently decided to change the MCU to a CC2540)

Empty Cup (higher resistance)

Full Cup (lower resistance)

### Words to PCBWay

I am almost done with our initial PCB design, but I am very novice, as this is my first design ever. It would be really appreciated if we could get our first PCB order free, before we send out a finalized design. We want to make sure that our design is accurate so that we can then order multiple PCBs. My project is not being sponsored or funded right now.
