Connection is shown below: Ground is common, ESP8266 is on 3. Steps for programming the ESP01 using an Arduino Uno: Install the ESP8266 board package in the Arduino IDE. If you are unfamiliar with relays (pinout, operation, programming, etc. Onboard the ESP8266 WiFi module has three work modes: STA (client), AP (hot), STA + AP (hot +client). Dengan memanfaatkan API dari Bot Telegram kita dapat menghubungkan perangkat ESP8266 dan Smartphone Android/IOS, Melakukan komunikasi antara kedua perangkat tersebut hingga membuat sebuah sistem kontrol berbasis internet chat yang mampu mengontrol relay lampu yang kita kondisikan berada didalam rumah menggunakan jaringan internet. Execute Command. On web there are a lot of kits that include relay, temperature and humidity sensor and more, all based on ESP8266-01s or ESP8266-01 WiFi module, see here. dd nt zl nj nf nl gb lz mh zo
