Arduino based Photo album and sketch toy. Simple functionality for browsing the photos on the SD card and sketching in different colors.

In order to keep the code small enough to fit into the 28k of the arduino micro I stripped the TFTLCD library and kept only the functionality I needed.

The code looks for "bmp" photos in the "/album" folder of the SD Card and displays them starting from a random point on each boot.

Top (navigation) buttons are (from left to right)

• show previous
• show random
• reload
• show next

Bottom buttons select the pen color for sketching.

Toy case created with OpenSCAD and printed with PLA.

• Arduino pro micro (leonardo) 5V
• TF-028 TFT touch screen (240x320) shield with sd-card
• 2x18650 Batteries in series (because I had some spare)
• Power switch
• Prototyping PCB

• TFTLCD-Library
• SdFat

PCB, arduino and LCD+touchscreen+SDCard_reader shield. Front and back views In order to save space the arduino goes between the PCB and the LCD board. After soldering the arduino to the PCB. It is a bit messy but it was my first try using a PCB this way. Testing basic h/w and s/w functionality. Assempling everything into the 3D printed case. Orange is a nice color for a little girl's toy :) Another view of the box. Since this is a kids toy, I secured all h/w in place with some hot glue. Maybe it will survive a few more hits this way! And this is the end result. The use of 18650 batteries made it a bit thicker than it would be if I had opted for for 2xAAA batteries and 3V H/W. But it has a pretty long battery life now!
