Ciao a tutti, posso chiedervi un favore?
Mi potreste aiutare passo passo ad usare questo sensore del link?
Dovrebbe avere secondo i dati sul sito un sensore VL6180 ed avere questo cablaggio:
Verde TXD
Bianco RXD
Blu SCL
Giallo SDA
Nero GND
Rosso VIN
ho cercato online tutorial vari ma non ce verso di farlo funzionare, se collego verde e bianco ad Arduino UNO invertendoli quindi TXD a RXD e RXD a TXD, vedo il led IR lampeggiare, ma nessun dato, cercando online ho trovato questo sketch, che poi sarebbe lo sketch di esempio della libreria, ma sia con il sensore collegato che non collegato ottengo sempre gli stessi dati.
Mi aiutereste a capire come collegarlo ad Arduino e a creare uno sketch per usarlo?
Grazie
