    Thank you for your quick response !
    I mean the Modular Chemistry Analyzer project,
    just the part of making multiport selector valve.
    I can not understand the mechanism purely.

    Caro Pasquale,
    l'esp8266 è stato programmato usando l'IDE di arduino (https://github.com/esp8266/Arduino). Per quanto riguarda il codice che ho scritto e le librerie che ho usato per i bot, dovrei controllare sul computer, ora non ricordo... Se ti servono mandami una email alla sezione contatti e te le allego appena ne ho l'occasione.
    saluti, dp

    Scisa, non avevo capito.
    Mi riferisco al progetto
    IoT: control esp8266 from Telegram Bot for telemetry and domestics applications
    Sto cercando di utilizzare un ESP-01 interfacciata con Arduino per utilizzare I Telegram BOT ma sono in difficolta' perche, mi pare di aver capito, che tutte le librerie disponibili non gestiscono I telegram BOT utilizzando I comandi seriali di ESP-01 ma utilizzano ESP-01 programmato tramite LUA.

    Darei quindi interessato alla tua soluzione.

    Grazie.

    P.S. Molto cortese nella sollecita risposta.
