This project was bootstrapped with Create React App, and also Adafruit CircuitPython

Go to https://github.com/influxdata/influxdb-client-python and follow the installation guide. We are using not using InfluxDB 2.0+ and above for this vending machine demo as it has a pricing plan, and limited functionality for open source buckets. See https://docs.influxdata.com/influxdb/v1.8/administration/config/ on how to set up environment variables and edit InfluxDB. Launch InfluxDB's command line interface in the bash terminal of your choice with

influx -precision rfc3339

Then, create a database named coins. For more information, visit https://docs.influxdata.com/influxdb/v1.8/query_language/manage-database/ Enter the following code into the InfluxDB CLI:

CREATE DATABASE coins

finally, enter exit to quit the CLI.

exit

The python script is intended to run on the Raspberry Pi. libatlas library needs to be installed to overcome errors caused by installing pandas, as pandas will fail to uninstall numpy. See https://numpy.org/doc/stable/user/troubleshooting-importerror.html?highlight=setup%20py To install system-wide the required python dependencies:

sudo pip3 install adafruit-circuitpython-matrixkeypad
sudo pip3 install pandas
sudo apt-get install libatlas-base-dev
sudo pip3 install websockets

• Read more and practise on rxpy and rxjs in preparation for InfluxDB querying and async py
