Perfect-Pour-Bar

Do you want to modernize your home bar experience while still maintaining that bar style feel? Here is a versatile project that can be easily modified to meet your own design. The goal of this project is to bring together a raspberry pi, touch screen, diaphragm pumps, and various electrical components to automatically pour six different drinks. Each of the six options can be quickly poured to either 0.5oz, 1oz, 2oz, and a free flow.

This project serves as a great beginners guide to programming graphical user interfaces(GUI) and learning to control mechanical components with digital call outs.

Setting up the Raspberry Pi 3A+

1. Download Raspberry Pi OS -----> https://www.raspberrypi.com/software/
2. Make sure to have the most resent vesion of Python Downloaded
3. Install Package installer for Python (pip) -----> https://www.raspberrypi.com/documentation/computers/os.html
4. Download GPIO Zero -----> https://gpiozero.readthedocs.io/en/stable/installing.html
5. Download GUI Zero -----> https://lawsie.github.io/guizero/
6. Run code on Boot (Use method 3 for running startup with GUI) -----> https://www.makeuseof.com/how-to-run-a-raspberry-pi-program-script-at-startup/

Setting up Touch Screen

To set up the screen follow the following instructions. (This may change depending on size and manufacturer of touch screen)

In terminal type:

git clone https://github.com/yoyojacky/52Pi.git
cd~/52Pi
chmod +x restool.sh
./restool.sh

Follow the steps and select the screen type you have and the correct resolution.

Run "Perfect Pour Code"

Copy, paste, and run the following code in Thonny:

Note: The 18 lines with "sleep(xx)" indicate the ammount of time the pumps will run. You will need to calibrate these with your hardware to get the desired pour quantity. For reference I found: 0.5oz = 1.1sec, 1oz = 2.2sec, and 2oz = 4.4sec.
