 ===== 5. Results and Discussion ===== ===== 5. Results and Discussion =====
-===== 6. Obstacles ===== +  * The concept has proven to be very much viable with all the requirements fulfilled in a prototype and ready to be moved to the next steps. 
-===== 7. Key Learnings ===== +  * Using MQTT for communication between the different devices has proven simple yet efficient.  
-===== 8. References =====+  * The e-ink display was a great choice for this project due to its high visibility in daylight and power efficiency. 
 +  * To display payer information, the payload of an MQTT message can be used. 
 + 
 +===== 6. Future Steps ===== 
 +  * Build a casing for the display component to keep it protected and portable without any fear of damaging connectors. 
 +  * Further develop the design of the text/images shown on the e-ink display. 
 +  * Figure out whether the Kalisto main website can be used to integrate this whole system or not. 
 +    * If not, further development of the web-application must proceed. 
 +  * Payment can be handled using [[https://docs.stripe.com/stripe-js/react|Stripe]], a comprehensive suite of tools for handling online financial transactions. 
 +  * Payer information should be stored in a queue like structure to give a chance for the display to show all donations. 
 +===== 7. Obstacles ===== 
 +  * It was also a difficult and challenging accomplishment of the particular system architecture to ensure high level expertise with precision. 
 +    * This can be shown from the different system architecture diagrams [[amc:ss2024:bird_feeder:kalisto:system_arch|here]]. 
 +  * Finds the correct pin configuration for between the XIAO ESP-32 and the e-ink display. 
 +  * The e-ink display cable broke at some point during the implementation and testing and another display was ordered to continue with the project. 
 +  * Just before the presentation, as there was another team using a RaPi and the same Nooie Pet Feeder connected on the same network, there was a conflict between both the 2 RaPis. This was solved by changing both the hostname and the port for one of them. 
 +===== 8. Key Learnings ===== 
 +  * The different communication protocols such as SPI and I2C. 
 +  * E-ink displays and how they function. 
 +  * Home Assistant and most of its features. 
 +  * Automation and triggers 
 +  * ESPHome and how its yaml syntax works. 
 +  * MQTT, Brokers, Topics, QoS, etc. 
 +  * Networking Basics.
