Scrooge McDuck - Real-time dollar quoting device
What it do?
This project was an overkill idea for a simple problem that I did purely for fun and to experiment with new things. Essentially, what it did was have a task scheduler that scheduled a process to run every hour. This process would collect the exchange rate of the Dollar compared to the Real, and then save it to Firebase. On the other side, I had a microcontroller with firmware written in C++ listening in real-time for the exchange rate. When it changed, it updated the display, and I would have an idea if it was the right time to convert my salary from dollars to reais.
