A stock display using a Nokia5110 LCD that shows a list of custom stocks and their daily trends. Uses the power of WiFi to update stock information every few minutes. Upward and downward trends visually indicated using a an RGB LED.
The stock website I used (AlphaVantage) did not have a functional intraday API at the time of creating this project so it currently updates daily. However that should be fairly easy to add in so feel free to use this project as a base!
I realize that LCD clarity in the picture is not the best but it reads "SNAP - 14.35"
NodeMCU 1.0 ESP-12E board
330 ohm 1% resistors
Because I'm too lazy to draw up the schematic...
