Adafruit – Potentiometer Knob – Soft Touch T18 – White
Adafruit: 2047
Description
Oh say can you see
By the knob’s early light…
Sorry – we thought that was clever. And while it wasn’t really, this potentiometer knob definitely is. It’s a ‘soft touch’ T18 knob that works great with our Panel Mount 10K, Panel Mount 1K, and Panel Mount 100K potentiometers. The knob is designed to set directly on the potentiometer’s ridges so it’s an easy & secure fit. It has a nice feel, with a rubbery grip, tweaking it is quite fulfilling.
This is the blue version and it has a nice deep color on the inside with a striking blue line on the outside for great visibility with whatever you’re making. We also carry it in white and red if you’re looking for a variety of colors.
Technical Details
- Diameter of the top: 11mm / 0.4″
- Diameter of the base: 15mm / 0.6″
- Weight: 1g

Adafruit – Standard LCD 20×4 + Extras – White on Blue
Adafruit: 198
Description
Standard HD44780 LCDs are useful for creating standalone projects.
- 20 characters wide, 4 rows
- White text on blue background
- Connection port is 0.1″ pitch, single row for easy breadboarding and wiring
- Single LED backlight with a resistor included, you can power it directly from 5V. If it’s too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights
- Can be fully controlled with only 6 digital lines!
- Built in character set supports English/Japanese text, see the HD44780 datasheet for the full character set
- Up to 8 extra characters can be created for custom glyphs or ‘foreign’ language support (like special accents)
- Comes with necessary contrast potentiometer and strip of header
For more information, check out our detailed step-by-step Arduino+LCD tutorial
We have a generic 20×4 datasheet that has dimensions and pin-locations (the exact model may vary but the pinout, size and protocol information is the same). We also have a HD44780 datasheet with the detailed commands for control.
