These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculates the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

Unit comes with adhesive backing. The connector is 0.1″ spaced and breadboard friendly.

Note: These potentiometers work great with fingers, or a stylus.

Features:

1. Ultraflat
2. Excellent repeatability
3. Customized design

Package Includes:

1 x SoftPot Membrane Potentiometer – 50mm

Potentiometers are the perfect tool when you want to change your circuit by turning a knob. Turns out, there are times when you want to adjust your circuit without manually turning a knob, and the DS1841 I2C Logarithmic Resistor from Maxim can do just that. It’s a programmable resistor, similar to an I2C potentiometer like the DS3502 I2C Potentiometer, so why another?

The big difference between the two is how the resistance changes in relation to changes made to the wiper. The DS3502’s resistance has a linear relationship to the wiper’s setting. Each time you change the wiper by a given amount, the resistance will change by the same amount. With the DS1841, the relationship between resistance and the wiper setting is logarithmic. This means that as the wiper setting changes, the amount of resistance will depend on where in the wiper’s range the current setting is.

Additionally, . This table allows you to specify the wiper setting for each of 70 temperature increments between -39 and 100 degrees C, plus one each for above or below that range. You can even manually set the wiper to one of the entries in the LUT.

We’ve put it on a breakout PCB with the required support circuitry and Spark Fun qwiic compatible STEMMA QT connectors to allow you to use it with other similarly equipped boards without needing to solder. QT Cable is not included, but we have a variety in the shop.  This handy little helper can work with 3.3V or 5V micros.

Features:

1. Working with the DS1841 is easy
2. The DS1841’s resistance ranges from 22kOhms to 3.7k Ohms and has 128 tap points
3. Log potentiometers are used in audio applications for things like volume control because they better match the response of human ear to sound.
4. The DS1841 can be configured to adjust its resistance based on temperature with hysteresis to keep things from jumping around
5. The temperature compensation can be adjusted by using the LUT (Look Up Table) built into the DS1841
6. It’s ready to get to work with a range of development boards
7. To make things even easier we’ve gone and written Arduino and Circuit Python/Python 3 drivers to simplify interfacing with your new knob-replacing friend

Packages Includes: 

1 x Adafruit DS1841 I2C Digital 10K Potentiometer Breakout – STEMMA QT Qwiic

This is a 10k Sliding Adjustable Linear Potentiometer. Linear Potentiometers are variable resistors whose resistance can be varied by moving the handle linearly from one end to another. The sliding potentiometer has two ends which means when the handle is at one end the resistance is 0 ohms and moving the handle towards the other end will change the resistance towards 10K as per the handle movement. The potentiometer comes with a plastic knob which gives the best feel for usage.

Features:

1. USES the high-quality slide appliances, stable and reliable performance
2. Dual analog output, 0 – VCC analog voltage signal

Package Includes:

1 x 10k Sliding Adjustable Linear Potentiometer
