Summary
Let's summarize what we achieved in this project. We used the ESP8266 Wi-Fi chip to grab the price of Bitcoin from a web API, and we displayed this price on an OLED screen connected to the ESP8266. Then, we also added two LEDs to the project to check whether the price is going up or down.
You can of course do many other things with this project. You can, for example, display the price of Bitcoin in currencies other than USD, and implement a switch button to change the display currency.
In the next chapter, we are going to see how to use the ESP8266 to monitor and, if required, water a plant (or a whole garden!) from the cloud.
