Solved after authorized the App to access at the smartphone camera. Hi, i had the same problem with the Android App wich doesn't work. Allow the app to use the Bluetooth and Camera. On the Android phone, you need to install the ArduinoTFT.apk. If the Arduino UNO board is successfully programmed, you can proceed to the next step. Download the ArduinoBluetoothCamera.ino demo sketch (and file ov7670_regs.h for camera init).Select the corresponding port to which the Arduino UNO is connected.Connect the USB cable to the Arduino UNO board.For simplicity, I recommend flashing it separately, without TFT shield. Then you need to install a library for TFT shield - /YATFT/YATFT (download the library and unpack it into the "libraries" folder in the Arduino IDE directory).Īfter installing the Arduino IDE, you must program the Arduino UNO board. Ģ0-pin (2.54 mm) connector for camera (OV7670).Īll demonstration sketches are written in the Arduino IDE environment, therefore at the beginning it is necessary to install the Arduino IDE.Ĥ-pin (2.54 mm) connector for connecting the Bluetooth module HC-05 (-06), ESP8286 WiFi module.RTC IC DS1307 with 3V lithium battery CR1220, Resistive touch screen (XPT2046 controller), Then, on the contrary, transfer the picture (image from the camera) from the Android phone to Arduino UNO and display it on the screen of a unique TFT shield.Ī special application was written for the Android phone. In this instructables, I will demonstrate how you can connect via bluetooth between Arduino and Android phone, get a picture from the OV7670 camera on Arduino UNO and transfer it to Android phone. Information about this logo is in these articles: article 1, article 2. And what if a little bit of help Arduino - to transfer all the "hard" work on the shoulders of other device? And there is such a device! Someone will say that this is impossible, Arduino is too slow to process large amounts of data with good speed. But I want to transmit not just a set of characters and numbers, but pictures. I want to exchange data between a mobile phone on Android and Arduino UNO through bluetooth in 100,501 times. 100,500 instructions were written on how to exchange data between a mobile phone and Arduino via bluetooth. Thanks to the Arduino platform, millions of people have discovered the wonderful world of electronics and programming. Today you can hardly surprise anyone with a mobile phone with a camera, wireless gadgets and other technical advances.
