After programming, you will only need to setup your Wifi and BTC address.
1. Connect to NerdMinerAP
- AP: NerdMinerAP
- PASS: MineYourCoins
1. Setup your Wifi Network
1. Add your BTCaddress

- [x] Bug memory leaks
- [x] Bug Reboots when received JSON contains some null values
- [x] Implement midstate sha256
- [x] Bug Wificlient DNS unresolved on Wifi.h
- [ ] Code refactoring
- [ ] Add blockHeight to screen
- [ ] Add clock to show current time
- [ ] Add new screen with global mining stats
- [ ] Add support to control BM1397
