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.
4 Position long strip, right angle female connector with 0.1" spaced centers.
A simple but effective Grove water sensor. Expose the electrodes to a drop of water, and the signal drops very low. Can be used with both analog and digital ports.
