An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components.

Crystal 20MHz

Standard frequency crystals - use these crystals to provide a clock input to your microprocessor. Rated at 20pF capacitance and +/- 50ppm stability. Low profile HC49/US Package.

7-Segment Display - LED (Red)

Your basic 7-segment LED. Common anode. Two decimal points, but only the one on the right is wired. Digit height is 0.6" (15.24 mm). Overall height is 1" (25.4mm)

$1.90

Rotary Encoder

This is a 12-step rotary encoder with a nice ‘clicking’ feel. It’s breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits. The unit outputs gray code so that you can tell how much and in which direction the encoder has been turned.

2.54mm or 1.0" Single Digit Alphanumeric Display - Red

Alphanumeric displays are pretty neat. Use them for numbers, use them for letters, or both. They are a good size and brightness for easy reading. The decimal points aren’t connected, so keep that in mind when ordering.

10 Segment LED Bar Graph - Red

These 10 segment bar graph LEDs have many uses. With a compact footprint, simple hookup, they are easy for prototyping or finished products. Essentially, they are 10 individual red LEDs housed together, each with an individual anode and cathode connection.

Rotary Potentiometer - 10k Ohm, Logarithmic

This pot has a ¼" mounting diameter and has a 10K logarithmic taper. Check the datasheet for dimensional drawings.

$1.25

Schottky Diode

Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with motor drivers such as the L298N.

$0.30

7-Segment Display - 20mm (Red)

For a long time we’ve had small 7-segment displays and huge 7-segment displays, but now we finally have something in between. These 20mm 4-digit 7-segment displays are big enough to see from a distance but not so big that you’d have trouble finding an enclosure for them.

Load Sensor - 50kg

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). This sensor can measure up to about 110 pounds. Check the video below for a simple explanation on how these work and how to use them.
