Adding a display to an embedded project often requires more effort than everything else. Not so with SparkFunโ€™s MicroView, which combines an Arduino-compatible board and OLED display in one small package. SparkFunโ€™s library makes drawing to the display similar to using Processing, with shapes, text, as well as slider and gauge widgets perfect for showing sensor data. It is a little over half an inch tall, which might get bulky on your wrist but would work as a tiny game platform, dollhouse TV, or even in a large necklace. One note: Youโ€™ll need to buy a programmer to upload your code.
