These simple switches are the Mechanical Bumper sensor for the SparkFun RedBot, giving you the ability to detect a collision before it really happens. When the "whisker" bumps into a foreign object it will make contact with a nut next to it, closing the connection and, by default, turning off the motor.

This is the LM3914 Dot/Bar display analog-controlled LED driver that uses an alinear output scale. With this driver all it takes is a single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain point turn on) or dot mode (with only a single LED on at a time).

This is a small chainable 1.75" (44.5mm) outer diameter board equipped with 5050 WS2812 RGB LEDs. The WS2812s are each addressable as the driver chip is located inside the LED. Each NeoPixel Stick has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5V.

They have a very fine tip which allows you to pick up very small parts with precision. This is a great tool to have if you're working with surface mount components or anything with very small parts. The ESD-safe coating will also help prevent electro-static damage to sensitive electronic components.

This is very similar to our BlueSMiRF modem, but it is designed specifically to be used with our Arduino Pros and LilyPad Arduinos. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target. We've tested these units successfully over open air at 350ft (106m)!
