<html><body> <h3>Device is equipped with touch screen which is used to change settings:</h3>- Four possible brightness levels ensures that it can be adjusted to sunny noon as well as dark night. - Change time of single image display to fit your preferences. - You can choose display mode, see images in random order or set only your favorite image permanently. - Set frame to automatically turn off after some time. <h3>Used hardware</h3>LCD screen https://www.waveshare.com/4inch-tft-touch-shield.html Arduino Pro Mini 5V USB C connector https://botland.store/protoboard-connector-board-accessories/12658-usb-20-typ-c-connector-for-breadboard-pololu-2585-5904422319823.html Power button https://botland.store/switches-with-button/10799-on-off-bistable-switch-pbw-12a-2a-250v--5904422316648.html All code can be found here: <a href="https://github.com/mboguslawski/Arduino-Picture-Frame/tree/master">https://github.com/mboguslawski/Arduino-Picture-Frame/tree/master</a><h3>Make one yourself</h3><figure><img src="https://projects.arduinocontent.cc/20078a8d-380d-4592-b9af-e2346d482c11.jpg"/><figcaption></figcaption></figure>Connect wires as shown in the image above. - Additional led can be put into button (if it will fit into your button) and connected via resistor to Arduino Vcc and Gnd - Capacitor can be added to smooth out any electric interference. - Add foam tape to the up section of display, it will be pressed against case lid to keep display in one place. - Screw usb port and button to the 3d printed lid. In the end it should look something like this: <figure><img src="https://projects.arduinocontent.cc/c961dbae-e22b-41e1-8b33-4c7c507f6bda.jpg"/><figcaption></figcaption></figure>Insert two nuts into dedicates holes in the lid as in the image below: <figure><img src="https://projects.arduinocontent.cc/35aa8f2b-495d-4f09-9beb-e32b35f6b313.jpg"/><figcaption></figcaption></figure> Close case with the lid with two screws, it is recommended to add some rubber on the bottom as shown below: <figure><img src="https://projects.arduinocontent.cc/0cb7cf6c-e251-44e7-a9d6-3f9d0ec8d167.jpg"/><figcaption></figcaption></figure> <h3>Quick start</h3>Once you build your frame, go to <a href="https://github.com/mboguslawski/Arduino-Picture-Frame/tree/master/recources/ui%20images">https://github.com/mboguslawski/Arduino-Picture-Frame/tree/master/recources/ui%20images </a>and put all .bmp files onto your sd card. Then you can add your photos in the following way: - photos must be in images sub folder - photo must be in bmp 24 bit format with exacly 320px width and 480px height - all photos must be named a number starting from 0.bmp, 1.bmp, ... Put sd card in frame and power it up using button. </body></html>
