I want to learn how to control hardware things like rotate a motor or sensors with android apps. Can you please suggest me how can i do that.
Hello,
Another solution is to drive your IoT directly from the web by using a web component and an ESP8286 board (programmable by using the same Arduino IDE). This is a bit tricker, but feasible as well with a little effort at the beginning ....
I have uploaded these tutorials on this topic to this community, you may be interested in taking a look.
Arduino + Bluetooth HC-06
Hello friends,
In this topic I am going to show some examples of Arduino UNO with the Bluetooth HC-06 module.
I will start with simple examples and later I will put some more complicated codes.
Arduino + Bluetooth HM-10 BLE
Hello friends,
I bought a wonderful HM-10 module with BLE for only $ 2.
I have written my experiences on this Spanish website (http://kio4.com/arduino/161_HM10_BLE.htm ) and I would like to share a summary in this Community.
I have used the BluetoothLE 20190701 extension.
I have connected the module to an Arduino UNO
[hc10_3]
I tried to use these libraries, but they did not work for me in Arduino UNO.
CurieBLE.h is for Arduino 101 (Curie).
ArduinoBLE is for Arduino MKR WiFi 1010,…
ESP32 - BLE (Bluetooth)
Hello friends,
I'll write in this topic about BLE on ESP32, send and receive text, with clock and without clock. Notify. I'll use the codes of Neil Kolban .
0.- Board D1 R32 ESP32.
This is a cheap card ($ 5) with the dimensions and shape of the Arduino UNO, but with the ESP32.

ESP32-CAM
Hello friends,
This is a cheap card ($ 6) with ESP32-S and a cam OV2640.
ESP32:
160MHz clock speed
RAM 520KB SRAM + 4M PSRAM
Bluetooth classic y BLE
Wi-Fi 802.11 b/g/n/
Cam: OV2640
SdCard reader.
Flashlight LED (GPIO 4)

ESP8266 - WiFi
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.
