10k Single-turn Potentiometer
We use this 10k single-turn trimpot in our own Sumovore Mini-sumo robot kit to set line detection sensitivity.
This NPN transistor is similar to the TR3904, but can deliver higher maximum current at better efficiency ratings.
Standard sized diffused T1-3/4 LEDs, great for indicators. Available in green, red, yellow, white and blue.
This tact switch is compact, inexpensive and can mount on most breadboards.
10 resistors each of 100ohm, 470ohm, 1k, and 2.2k
5% accuracy 1/4 watt resistors to get you started with your BEAM experiments.
For moving things in a straight, STRAIGHT line, you need linear rails!
The Lux Spectralis is a deluxe RGB blinky that you can build, with over 30 flashing, blinking and glowing modes.
