Availability: Back Order
Item #: COM-09117 -

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. This unit does not come with a knob, but a working knob is related below. Documents: Bildr example showing how to use an encoder in...

Availability: Back Order
Item #: COM-09277 -

This a simple breakout board for the button pads. Each LED and button is brought out to the side connectors. The connectors are soldered to the back side of the PCB. We recommend trimming the connector leads on the button side as short as possible to reduce the deflection of the pad. Now with footprints for diodes! Use the super cheap 1N4148 through-hole diodes. These can be used to isolate the switches to make for a bit easier decoding. Documents: Schematic Eagle Files ...

Availability: Stocked
Item #: COM-09288 -

An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user! This is a center-tap linear type potentiometer. The outer two pins will always show 10K resistance, the center pin resistance to one of the...

Hall-Effect Sensor - US1881 (Latching)
Price: $2.13
View
Availability: Stocked
Item #: COM-09312 -

The US1881 is an integrated Hall-Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage,...
