Adafruit – Panel Mount 100K potentiometer (Breadboard Friendly) – 100KB
Adafruit: 1831
Description
This potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 100K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2″ apart with pin-points, so you can plug it into a breadboard or perfboard. Once you’re done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

Adafruit – Panel Mount 1K potentiometer (Breadboard Friendly) – 1K Linear
Adafruit: 1789
Description
This 1K potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 1K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2″ apart with pin-points, so you can plug it into a breadboard or perfboard. Once you’re done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

SparkFun – Infrared Emitters and Detectors
SparkFun: SEN-00241
Description: Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.

SparkFun – Small Stepper Motor
SparkFun: ROB-10551
Description: These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as long as you adjust the current level to 400mA or less. If using a non current limited driver (like a L293D or an H-bridge) you will need to lower your input voltage to keep the motor current below 400mA.
This is a Bipolar motor.
Features:
- Stride Angle (degrees): 7.5
- 2-Phase
- Rated Voltage: 12V
- Rated Current: 400mA
- 3mm Diameter Drive Shaft
- 4-Wire Cable Attached
- In-traction Torque: 100 g/cm
