Story

Inspiration

I had trouble in viewing my favourite stock prices by taking out phone constantly, s I have build a 24x7 Display Stock Price Tracker so I can get updates regularly

What it does

It fetches Stock Price from FinnHub API and Displays it on Aafruit TFT Display using ESP8266

How we built it

I first started with interfacing the Display with ESP8266 using the below pinout
We use the SPI Interface of the Display , Connect MOSI, SCL,Data,Reset, 3.3V and GND of ESP8266 to respective pins of the Display according to Pinout of Arduino Shield
You can use either the SPI Pins on Digital line or from ICSP header

Then I coded the part to connect Wifi with ESP8266
Further I created API key on FinnHub ,and tried parsing its data of stock symbol
Then Calculated the Previous Price and Percentage of Fall or Rise and Displayed it with GUI functions.
Added many Stock Symbols and then it automatically displays the data at API call per 3 seconds
