I am trying to use MIT App inventor to display data from Arduino via ESP 8266. I am finding it difficult to find an interface to show the data. What should I use to display real-time changing data?
Here an example with ESP8266
Hello friends,
1.- Send message and view it on an LCD screen.
1.- You write a message in TexBox1 and it is sent by WiFi to ESP8266, that message is shown on the LCD screen.
2.- If you write on5, off5, on6, off6, LEDs 5 or 6 turn on/off.
[esp8266_kio4]
```
// Juan A. Villalpando.
// KIO4.COM
// Send a message
// from App Inventor
#include <ESP8266WiFi.h>
const char* ssid = "Name_Net_WiFi";
const char* password = "Password_WiFi";
// Static IP.
IPAddress local_IP(192, 168, 1, 12);

Hello friends,
I would like to share my experience on uploading files to ESP32. At first I wanted to upload the files from the App using the Web component, but so far I have not been able to, so I used the ActivityStarter component and the device browser.
I'll be using this board, which is the shape and size of the Arduino UNO, with the ESP32.

Can a similar example be found in English language?
I am working on making a real- time parking lot scenario with clock usage. If any example related to this is found in English, it would be very useful

Hello friends,
I’ll write in this topic about WiFi on ESP32, LED on/off, Static IP, SoftAP,…
0.- Board D1 R32 ESP32.
This is a cheap card ($ 5) with the dimensions and shape of the Arduino UNO, but with the ESP32. I used this card in the ESP32 and BLE tutorials .

This card has classic Bluetooth, BLE, WiFi, ADC, DAC, and more feature.
This card can be programmed with the Arduino IDE.

The codes for ESP32 are similar to ESP8266. ESP32 has better features than ESP8266.
MQTT and IoT are great friends.
