732 MCP23017 - i2c 16 input/output port expander
732 MCP23017 - i2c 16 input/output port expander
US$5.17
Add another 16 pins to your microcontroller using a MCP23017 port expander. The MCP23017 uses two i2c pins (these can be shared with other i2c devices), and in exchange gives you 16 general purpose pins. You can set each of 16 pins to be input, output, input with a pullup or open drain.

727 Battery Holder 3 x AAA with On/Off Switch and 2-Pin JST
727 Battery Holder 3 x AAA with On/Off Switch and 2-Pin JST
US$3.42
Fits any standard AAA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkalines, the output will range from 4.6V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V

725 Terminal Block - 3-pin 3.5mm - pack of 5!
725 Terminal Block - 3-pin 3.5mm - pack of 5!
US$6.92
These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy to adjust with a screwdriver, and not too chunky. The only down-side is that they do not fit into 2.5mm spaced holes (they're 3.5mm spaced) - but they do fit in most perf/proto-board if you rotate them diagonally.

711 DC Toy / Hobby Motor - 130 Size
711 DC Toy / Hobby Motor - 130 Size
US$3.42
These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting.
