# Simple Arduino Crypto Display
### NOTE: Coinmarket cap have changed their API and this project currently does not work with it

[Check out the youtube video of the project!](https://www.youtube.com/watch?v=2IRsOFaWfho)
A display built with an ESP8266 that fetches live currency prices directly from the [CoinMarketCap.com](CoinMarketCap.com) API.
I've tried to make this project as easy to make as possible. There is no soldering and you also do not need to know how to code. In total it should take 10-15 minutes. The total cost is also only about $8 or so.

### Wiring
It should be wired as followed
| Pin On Display| Pin on NodeMCU |
| ------------- |----------------|
| GND | G |
| VCC | 3V (some boards say 3.3V |
| SCL (Sometimes SCK) | D5 |
| SDA | D3 |
---
NOTE: Some displays have GND and VCC swapped around, always wire as above!
