Arduino + Bluetooth HC-06

Bluetooth HC-06. Arduino. Send. Receive. Send text file. Multitouch. Image

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

HM-10. BLE. Arduino UNO. Notify. Bluetooth. AT. iBeacon. Arrhythmia

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)

BLE ESP32. Bluetooth. Send. Receive. Arduino IDE. Multitouch

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. [esp322pin_h] Search images: D1 R32 ESP32 This card has classic Bluetooth, BLE, WiFi, ADC, DAC, and more feature. This card can be programmed with the Arduino IDE. [comparativa] There is another smaller ESP32 mode…

ESP32 - WiFi.

ESP32. WiFi. WebServer. LED on/off. Static IP. Soft Access Point

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.

ESP8266 - WiFi

App Inventor sends information to ESP8266 by 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.
