A display built with an ESP8266 that fetches live currency prices directly from the 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
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!
