20-pin (2.54 mm) connector for camera (OV7670).Īttention: It is necessary (!) To use a 6-12 volt power adapter to operate the TFT shield, because the maximum current of 500 mA from USB is not enough for normal operation.Īll demonstration sketches are written in the Arduino IDE environment, therefore at the beginning it is necessary to install the Arduino IDE.4-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. Information about this logo is in these articles: article 1, article 2 In this tutorial, 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. 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 over bluetooth in 100, 501 times. 100, 500 instructions were written on how to exchange data between a mobile phone and Arduino over 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.
