Video: Yooj Yim Bitcoin Ticker: 6 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Nov yog Bitcoin yooj yim lossis lwm yam ALT npib Ticker.
Qhia Ib Leeg Npib Nqe ntawm 8x 7 ntu Zaub.
Cov zaub loj, ci thiab nyeem tau yooj yim.
Tus nqi tsocai los ntawm coinmarketcap.com dawb API tau hloov tshiab txhua 5 feeb.
Luam yooj yim thiab tsim.
Code tus lej raws Hector de Isidro ua haujlwm:
Kauj Ruam 1: Tshooj Npe

5x Txiv neej Pin Header Connector
2x x5 Poj Niam Dupont Cable Jumper Hlau Pin Header Vaj Tsev
22 AWG AWM
2 x 3M screws
4 x 2 M pin
Kauj ruam 2: Luam tawm
Cov ntaub ntawv STL muaj nyob ntawm:
www.thingiverse.com/thing:3620420
1x Yooj Yim Bitcoin Ticker Box
1X Yooj Yim Bitcoin Ticker Npog
Kauj ruam 3: Electronics
Txuas 5 tus txiv neej lub taub hau rau NodeMCU Pawg Thawj Coj.
- 3v xov
- xov gnd
- dataPin = D5
- csPin = D6
- clockPin = D7
vin - 12v DC fais fab tuag
g - lub zog qhov av
Kauj Ruam 4: Coinmarketcap.com API
Tsim tus as khauj dawb ntawm:
coinmarketcap.com/api/
Luam API Key koj yuav xav tau nws hauv qib tom ntej.
Kauj ruam 5: Code
Nruab LedControl Library siv Tus Thawj Saib Xyuas Haujlwm hauv Arduino IDE.
Rub tawm Simple_Bitcoin_Ticker.ino los ntawm:
github.com/Nimrod-Galor/Simple-Bitcoin-Tic…
Qhib Cov Ntaub Ntawv Hauv Arduino IDE thiab hloov kho kab:
- #define STASSID "SSID"; (Qhov SSID yog koj lub npe network WiFi.)
- #define STAPSK "PASSWORD"; (Qhov twg PASSWORD yog tus password network)
- const String API_KEY = "API_KEY"; (Qhov twg API_KEY yog koj li coinmarketcap.com API Qhov Ntsuas)
Upload Sketch rau NodeMCU.
Kauj Ruam 6: Sib dhos
- Txuas Zaub rau Lub Thawv.
- Txuas dc Jack rau Box.
- Ntsia PBC rau Lub Thawv.
- Txuas Lub Hwj Huam IN hlau.
- Txuas Cov xov hlau.
- Txuas NodeMCU Pawg Thawj Coj.
- Pop ntawm Npog.
Txuas mus rau DC 12V lub zog siv hluav taws xob, tos ib pliag thaum NodeMCU txuas rau koj WiFi, thiab Koj Ua Tiav!
Txaus siab rau.
