Hi @Doudy
In my case the extension cable is used between the ultrasonic sensor and my D1 mini because the distance wasn’t sufficient.
For my part the D1 mini is connected to a phone USB charger
Thanks for the reply
You don’t specifically have to use this cable?
The cable’s connectors don’t have to match!
Would a « phone » cable with 4 wires also work?
Generally I take an old USB cable. ( those from our old printers are quite long)
Good idea
Hello jerome,
I’ve just started the
But I’m stuck here :

Now, you must download the libraries necessary for the code to work.
We will need:
- ESP8266Wifi
- PubSubClient
I can’t find ESP8266Wifi in the « Library Manager »
There is « ESP_WifiManager » or « ESP_WifiManager_Lite »!
GitHub says:
This is an ESP32 / ESP8266 WiFi Connection Manager with fallback web configuration portal. Use this library for configuring ESP32 (including ESP32-S2 and ESP32-C3), ESP8266 modules’ WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson
Which one should I choose?
Hello @Doudy
You open your Arduino IDE, then go to File, Preferences and at the bottom in « Additional Boards Manager URLs: » you paste the line below
http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
afterwards you install the boards and you’ll find them.

No matter how hard I search the libraries, I can’t find ESP8266Wifi
or am I 
See if you can find this one ESP8266WiFi, with a capital F
yes it was done
ESP8266WiFi is used to include the library in the code, so yes, normally it’s fine.
It’s line one.
You click on it and it inserts line 1 #include … into your Arduino code, as Jerome tells you
So, I ran a test after connecting the cables, uploading the code and adjusting the variables.
Result:
Executable segment sizes:
ICACHE : 32768 - flash instruction cache
IROM : 249268 - code in flash (default or ICACHE_FLASH_ATTR)

Your code seems to have uploaded successfully.
If you connect it to your PC and open the serial monitor with the Arduino IDE, do you see any output to test?
Sorry but I don’t understand!
